A blog about what I eat. Whoopee!

Vegan Cats

Posted by tinako on January 24, 2010

I think most vegans feed their cats regular commercial cat food.  I do.  We just sort of accept that if we decide to have a cat, that is what cats eat.  But it bothers me that, while human veganism is often discussed reasonably, most discussions about feline veganism, even among vegans, involve verbal frothing at the mouth.  Reason and logic seem to fly out the window.

Maybe this negativity is justified, but so much of it seems to be circular in reasoning.  The number one reason given against vegan cat food is that (all together now) “cats are obligate carnivores.”  All that means is “they have to eat meat.”  So: they have to eat meat because they have to eat meat.  I wish we could ban that pat phrase from discussions and move on to some actual facts, such as who decided that and what it’s based on.

It’s probably primarily based on the fact that cats naturally eat nothing but meat in the wild.  Grass is just for digestion.  OK, but that does not automatically prove that they would not be healthier on an “unnatural,” vegan diet.  We vegans hear that same argument when cavemen are dragged into discussions.  Who cares what cavemen ate?  Luckily studies prove that well-planned veganism is very healthy for humans, so we humans don’t have to put up with that reasoning.

In addition, pet cats do not live like they would in the wild – they are inside sleeping in fuzzy beds and gazing at the fish tank, not stalking prey in the snow.  And most commercial cat food is a conglomeration of the worst parts of the most ill-treated animals – beyond the misery involved, which is outside the scope of a discussion on whether vegan food is healthier, this flesh is so beat up it’s not allowed for human consumption.  But people get apoplectic at the thought of someone substituting a thoughtful plant-based diet for that factory crap, because it’s not “natural.”  Blech!

We’re getting to better arguments when people start talking about nutrients.  But the nutrients that we know about are all available in plant or synthetic form.

I think the best arguments will point out that there seem to be some formulation problems with some of the commercial vegan cat foods.  The two I know of, Evolution and Vegepet, were found in a test to be nutritionally inadequate.  One producer denied this and another fixed it.  Wikipedia seems to have a reasonable discussion about this topic.  It’s not clear to me why vegan cat food manufacturers can’t solve these formulation problems and prove it, so we can all move on.

It turns out that thousands of cats eat this cat food, and I was unable to find a single complaint where someone who actually fed their cat these foods felt it made them sick.  Google “Evolution Diet cat complaint” or “sick” and you will find nothing.  Same for HAINA.  The BBB has two complaints against Evolution Diet, both regarding shipping issues.  I couldn’t find any BBB record of the Vegepet manufacturer, HAINA.

But not everybody posts their negative response where Google can find it.  Colleen Patrick-Goudreau said that she felt her cats did better on meat cat food, I believe because one of them became ill on vegan cat food.  The Evolution Diet web site says that male cats may have trouble and should perhaps not be fully vegan.  They recommend a urine test to check the pH.  We as pet owners have to weigh all this information ourselves.

But none of these arguments supports the conclusion that cats cannot be vegan – that is, that no non-meat food invented ever (as in the future) could be healthy for cats.  I am not sure how anyone can prove that argument.  The best the nay-sayers can reasonably try to prove is that there is no suitable commercial vegan cat food right now, and that it is not currently known how healthy vegan cat food can be prepared.

Here’s my experience.  I decided to put my 15 yo cat on a 75% vegan diet (Evolution dry) because she was diagnosed with liver cancer.  The vet said there was nothing they could do, and I wanted to see if cutting her animal protein would help.  She was given 3-12 months to live 3 months ago.  She looks better than ever.  Her fur, which had turned brownish over the summer, is starting to come in black again.  Fur turning orange like that can either be a result of more licking (due to allergies, etc. – she wasn’t doing that), or due to severe protein deficiency, which can be caused by kidney or liver failure or intestinal disease.

She has two of those, because she also has kidney failure, 15 months now.  Because we were replacing her Rx kidney diet with non-Rx vegan food, my vet and I have carefully monitored her renal figures, which have improved slightly since the change.  (FYI her treatment for 12 months has been 150 ml Sub-Q fluid 3x per week, and 1 month of Fosamax 1x per week (experimental therapy decided on 2 months ago, but not begun until after renal panel showed improvement on 50% vegan diet alone).  Neither of these treatments bothers her much).

I sprinkle brewer’s yeast on the vegan cat food, and I can’t pry her face out of the bowl.  And you would never know she was sick – she is alert, sleek, plays with my kids, eats and drinks well.  This is one reason I am so determined – her quality of life is absolutely worth maintaining.

When I asked for help at message boards three months ago, trying to find phosphorus levels in different vegan foods, I got so much negativity, even though I deliberately never mentioned I was vegan myself, since that had nothing to do with my decision.  People literally told me I’d be torturing my dying cat.  They were incredibly mean at a very difficult time, calling me selfish, that I was doing this for me, to try to drag out her death.  I know she’s not going to live forever, but why wouldn’t I want to try to help my cat?

It’s way too early to make any kind of claims, but so far so good.  The owner of Evolution Diet (who I freely admit seems kind of flaky – but that doesn’t mean he’s wrong or lying) told me that he has had many cats at his shelter with exactly my cat’s issues (kidney failure and cancer) live healthy for many years on his cat food.  I based my decision on The China Study, but it was nice to hear his experience.

I’m not pushing vegan cat food, I just think there should be more reason and less venom in the discussion.  There don’t seem to be studies, actual science-based information, on vegan cat food.  We are left to try to find information for ourselves in a very hostile environment.

    That there is not much science on this is perplexing. I wish the manufactures of these foods would commission some independent research to determine whether their products are healthy (maybe they have and choose not to release the findings). Have you noticed that when there is no science on a certain dietary matter people simply act as if there is – inventing arguments that aren’t based on evidence and advocating their opinions religiously. T’is very annoying.

    I never gave a second thought on the fact(or the statement),”cats are obligate carnivores”. Giving my cat vegan food was just never occurred. But as you said in the article, indoor cats live completely different life style, they don’t have to go after small animals to feed them. It kind of makes sense that they “may” be suitable for different diet than they are used to. I would love to know the update on your cat condition&well being with Evolution diet. Bookmarked your site. Thank you very much.

    This is a vegan site with a forum on problems with evolution cat food. It’s great because it all vegans who have put their cats on this diet, so no angry omnivores yelling.

    I had my kitty on Ami cat for 5 months and she loved it. But am not able to afford more Ami cat so am feeding her wellness meat kibble for now. My friend has vegan cats and they are doing great. But so many cats have problems that I don’t want to risk her health. Nor can I afford any serious health problems for her. Hope u find the sit helpful.

      Thanks, Olga. That is a really interesting thread, and I would encourage anyone considering vegan cat food to consider those experiences. It is nice to read reasonable people discussing the issue reasonably. I think if I read that before I started with my cat and didn’t have the cancer issue, I would be pretty nervous. It does seem like the majority of cats do well (they just don’t get the press time) but it also sounds like Evolution might be as flaky as they seem from their own web site.

      Interesting about the cancer cat with “one month to live” who is “still” (2003) going strong, even after being taken off Evolution. I would like to know more about that.

      The thread is mostly over 5 years old. I wonder what has been happening since.

    Hey Tinako, interesting post, and great to hear your kitty is doing well!

    I used to think feeding cats a vegan diet was insane and, in a way, was enforcing your beliefs onto your pet.

    However, this reason for feeding your pet vegan made sense to me – your cat would never, in the wild, hunt down a cow/sheep/pig. He would never eat canned, processed food. And that aside, purchasing traditional meat-based petfood supports the nasty business of industrial agriculture, which, if your cat was wild, he would also not be supporting. There is nothing natural about your standard catfood, and vegans don’t put their money into industrial agriculture.

    • tinako said

      Yes, I can see both sides myself – my cat is not vegan, I am. But the more I think of it, the more uncomfortable I am with conventional commercial food, which creates a market for the most mistreated animals. I don’t usually buy into so-called “humane meat,” but supporting the worst practices is pretty revolting.

      To be clear, as strong as my vegan values are, this decision was all about the cancer.

      It was my exact hope in posting these thoughts that people would give the idea a fresh look. Thanks for stopping by.

    Mini-update. My cat’s labs are still fine but she has been losing weight for some time. She was overweight and does not look bad yet, but I want the weight loss to stop. While she would eat the Evolution dry with nutritional yeast on it, alone it was clearly not her favorite food. I read about Ami cat food, and while I couldn’t find a lot of info on it, pet owners were saying their cats really liked it. I ordered some and Ella does like it much better. She is definitely eating more food, so hopefully at her next appt in 6 weeks she will have stopped losing.

    This is the only place I found selling it in the U.S.: http://store.veganessentials.com/ami-cat-vegan-cat-food-p2246.aspx

    Another mini-update. Ella LOVES the Ami cat food, and gained a little weight back at her last checkup. So yay for that. While she has stopped the minor table begging she did while on Evolution, I think her coat might not be as shiny and smooth recently. But then, she is a pretty sick cat, so it’s hard to blame that on Ami. If I had cancer and kidney failure, my hair might not look so great either.

    However… while her creatine level continued to drop a little (the vet said this is the most important indicator for her kidney health), her phosphorus, which had been pretty stable since she was diagnosed over a year ago, came up suddenly. We can feed her a paste to bind to phosphorus, but unfortunately it is meant for humans, tastes like mint, and cats hate it so much it can put them off their food. So I suggested I back off a bit on the Ami. I had finished off her K/D (kidney diet) dry Rx food and not replaced it so she was getting all Ami, with maybe one can of K/D per week. I’m not sure whether it was the switch from Evolution to Ami or ending the K/D dry that has affected her phosphorus. So I will go back to maybe 3:1 Ami to K/D dry for the next month. If her next test still isn’t good I could go as low as 1:1 and still, according to my calculations, keep her animal protein at 10% of calories (for her cancer).

    She’s still active and happy seven months into a 3-12 month prognosis – I wonder if her cancer is growing.

    • tinako said

      You can now buy a tasteless powder to bind to phosphorus, but you have to sprinkle it on their food a few times a day, which sounds like a pain, so I’ve solved the problem by adjusting her food instead. Anyway, it’s Aluminum Hydroxide and you get it from ThrivingPets.com. You don’t need a prescription but definitely work with your vet.

      • tinako said

        (Update that we did end up using this and it wasn’t so bad and definitely helped her chemistry for the last few months. We normally fed her dry, which did not work with the powder, but for this we mixed the powder in with a teaspoon of canned a few times a day, which she certainly didn’t mind.)

    Hi Tinako,
    I am considering switching my cats to a vegan diet as well. One of my “babies” is pretty overweight while the other is pretty slim. It has been a struggle to balance the two extremes. I am most concerned with the extra weight of my heavier cat. He had a serious surgery three years ago that resulted in removing his “man part” after three unsuccessful attempts to remove urinary blockage. At the time, we were living in a home that had developed toxic mold- my fiance and I both became sick as well. We feel his problem was rooted with the toxins combined with his weight and thus inability to filter them efficiently. Anyway, I love him soooo much and want him to live as long as possible. He is 6 years old now. I just began “Green Mush” from the VitaMineral Green Company. I mix it into his Organix cat food and he loves it. What is your take on vegan wet food? What happened with you darling that was diagnosed with cancer?

    • tinako said

      Ella is still doing fine at 10 months into her 3-12 month prognosis. She is still losing weight slowly, which I would rather was not happening, but other than that she is active and happy and passing all her tests. The only thing I notice different about her is that, while she is clearly very content, she used to be a very loud purrer and now I seldom hear her purr.

      As I mentioned, I’m now mixing it half and half with her Rx kidney diet food, since 90% Ami caused her phosphorus to creep up. After a month at half-and-half it went back where it should be. I may bump the Ami ratio up a little bit; I want to push the edge here to give her as much vegan as I can to keep her liver healthy without hurting her kidneys – it’s a balance.

      Sorry, the only thing I know about wet vegan food is that my cat didn’t like Evolution’s very much. Or their dry. She likes Ami a lot, but I don’t think they make a wet.

      Because my cat’s renal failure brings her to the vet every couple months for a test, I am very comfortable feeding her vegan cat food. Healthier cats who would otherwise only go once a year may need closer monitoring than they would otherwise get. As I mention in my post, I think theoretically a vegan diet could be fine, but I’m not convinced the manufacturing has caught up with the theory.

    tinako, i found your post to be well-thought out and presented as is your blog. you may be interested in this:

    http://www.30bananasaday.com/group/30badinternetoutreachguerrillas/forum/topics/veg-pets-dogs-and-cats?xg_source=activity

    as well as various discussions along these lines on the 30bad forum. if you can’t find them, you are welcome to contact me and i’ll dig some of them up.

    we have fed several veg cats for several years. they eat mostly hoana products though we give a bit of evolution kibble too (though i’m questioning the ‘manufacturing’ vs the ‘theory’ on them too).

    in friendship,
    prad

    • tinako said

      Thanks, Prad.

      Funny how no one, including Peta, seems to have heard of Ami. (http://www.peta.org/living/companion-animals/Vegetarian-Cats-and-Dogs.aspx)

      It’s too bad the one article about a vegan cat (mainstream press – http://www.telegraph.co.uk/news/newstopics/howaboutthat/5148172/The-UKs-only-vegetarian-cat.html) had so many predictable disclaimers about how impossible this cat’s diet was, that old “obligate carnivores” chestnut. It was illogical in an article about a cat that is obviously not. I can understand that they didn’t want people to see the article as cat-feeding advice, but they could have said that while acknowledging that perhaps we don’t know everything about what cats need to eat, the obvious conclusion from the facts of that case.

      I’m glad to hear you’ve had good results with vegan cat food. My Ella is still doing fine at 12 months into her 3-12 month prognosis. Her vet is amazed and the secretaries tell me she’s a celebrity there.

      Thanks for stopping by – Tina

    You haven’t mention Veganpet Cat and Dog Food so I thought I would.
    Veganpet Cat and Dog Food is the ONLY vegan pet food on the market that has met (and passed in some areas) AAFCO and NRA standards.
    It’s all human grade; mostly organic and as of this week comes in dry AND canned versions.
    I’ve linked the facebook page above which has most of the information on the food there including the producers website.
    My cat is on the food and has been since I got him at 8 weeks and I know many other cat and dog owners who feed this to their cat.
    Look into it!

      Thanks, Brendon. Great to hear your pets are doing well on vegan.

      Because I seem to have finally worked out the maximum ratio of Ami Vegan to K/D Rx Kidney dry food to keep her phosphorus in check, I need to stick with what I’ve got, give Ella a break from monthly blood draws, but thanks so much for the tip. I seem to get a lot of visitors here so hopefully it will help people. Funny how there doesn’t seem to be a really comprehensive list of vegan cat food.

      Update: Ella is almost 14 months into her 3-12 month prognosis and looks great. I asked the vet how we would know what was going on with her liver cancer and she said it probably would not show up on any tests until it was quite advanced. It was caught Oct ’09 on an unrelated ultrasound and I was half-expecting they would be doing another this time so we could have a peek but they didn’t need to. But the vet is surprised she is doing so well.

      She had a routine annual urine test which showed an infection, common with kidney cats, so after 4 weeks of antibiotics she had gained half a pound, which is huge for her. Her vet thinks her gradual weight loss might have been related to a long-term infection. She never looked too skinny though, she looks good.

      Feeding details for those with a similar problem (kidney + cancer): As I said her phosphorus is now good after months of fiddling to find the highest ratio of vegan she could have (it’s 2 Ami to 1 K/D, with 3:1 being too much; she also gets about 1/2 can of K/D wet per week to help with the SubQ injections). By my calculations she is getting up to 7% of her calories from animal protein (2 parts vegan has 0% animal protein, 1 part k/d has 20% mystery protein*: 1/3 of 20% = 6.66%), whereas Dr. Campbell’s rats stopped their cancer at 10%. So she is well within there and I feel pretty good about that.

      (* mystery protein – 20% calories from protein figure calculated from K/D website and an online protein calculator I found for diabetic cats. But I can’t tell how much of the K/D’s protein is from animals vs. plants)

    Our good kitty Ella died two weeks ago: http://expandingcircle.wordpress.com/2011/05/11/goodbye-ella/

    Tinako, I’m so very sorry for your loss. I ran across your thread as I began to look into a vegan diet for my two cats. I got these two in March, after losing my darling Cammy to kidney disease in February of this year. Your efforts on behalf of Ella were generous indeed, and I am so happy that this lovely cat had you to care for her through the end of her life.

    Cats are obligate carnivores so they eat meat is a circular argument? How about this? Cats have evolved as obligate carnivores. Their digestive systems are designed for eating meat. Humans evolved eating meat and fruit, then switched to grains, dairy, vegetables, fruit and meat. Our digestive systems are unspecialized, so we can basically eat whatever we want. Not true for cats. You keep talking about cats on vegan diets getting kidney disease from lack of protein. Do you know where cats get their protein? Meat. And yet you say that a vegan diet is healthy for cats.

    • tinako said

      I don’t recall asserting that a vegan diet is healthy for cats. My comments are that I wish there were more reasonable arguments. Yours is a much better argument than the typical one: it seems reasonable that switching from carnivore to vegan is very likely different than from omnivore to vegan. But still it is not proof that it can’t be done, just that it is likely not as easy.

      I also don’t see where I ever said that cats on vegan diets get kidney disease due to lack of protein. I have no real idea what causes kidney disease. I’m not sure if you’re referring to kidney failure, which in my cat was long before I switched her to half vegan. She was on regular food when that happened. Or perhaps you’re wondering about my juggling meat vs. vegan food for my cat once she had both cancer and kidney failure – that was because the meat food was special prescription low-phosphorus food, and I’m not aware of any low-phosphorus vegan food. I don’t see any reason it couldn’t be made. It had nothing to do with her needing meat – I would have put her on all vegan if I could have found a suitable prescription vegan food. Or maybe you mean kidney stones, problems which some pet owners have reported with some brands, Evolution being the only one I know of. I think that had to do with pH, and it would make sense since animal protein is more acidic than plant protein. This is not lack of protein but its pH, and I never made the connection you suggest, since I really don’t know.

      This is my whole point, we don’t know. I think I’m pretty clear that I’m not pushing a vegan diet for cats. Maybe it’s terrible for them. But I don’t see any evidence of it, either logical or clinical. Some cats seem to do really well on it. If it’s bad for them, every one of them, by carnivore definition, as many people claim, how are those healthy cats explained?

      You say cats get their protein from meat. In the wild yes, but I presume you know that there is protein in plants. I don’t mean to be insulting, I’m just not clear from your last few sentences that you know that. Vegan cat food has protein.

    I’ve been feeding my cat Vegecat by Hoana for a few months now. She’s just turned 15. I started by buying a can of veggie only cat food to see if she’d even go for it. To my great surprise she devoured it. So I bought the ingredients from Hoana… VegeCat and VegeYeast, and Prozyme Plus, and now I make her food using one of their recipes… and I add a little of the canned veg cat food or baby food. She’s really quite eager to eat her food. However, I have noticed that her weight has definitely gone down. She’s seems happy, still purring and happily stretching… but her back leg area is starting to concern me… weight wise. So I’m thinking of doing a split of canned non-vegan food with her vegan food… and see if a) she’s interested and b) it helps with her weight.

    Great blog by the way… nice to hear what others have tried and how it’s worked or not worked for them.

    And I am very sorry for the loss of your dear Ella.

    I am vegan, and my three cats and one dog have been vegan their whole lives. My 10 year old cat is like a 3 year old, the vet is always completely astounded by her excellent health. I am a nutritionist, and FYI humans are frugivores, not omnivores and certainly NOT carnivores. A living being needs nutrients, and does not care how it gets them. That’s why a vegan diet, when ensuring those nutrients are available, is just as successful as a dead carcass diet for a cat, or indeed any living being. Best of luck!
