Firstly (and most obviously) a disclaimer, neither of us are vets. Ruth has studied animal nutrition at degree level but no one is professing to be an expert in feeding cats a vegan diet. We have done a great deal of research into this topic and believe we have all the information that we would need should we rescue cats. As per usual if you have any questions or comments you can email us, leave a message under this post or write on our facebook page/group.
Similarly to the dog issue, when we as vegans oppose speciesism it is less than ideal to feed our companion animals other animals over the course of a lifetime. Veganism is unnatural for cats they say, well so is feeding them (for just two examples) environmentally-destructive cows or fish from the overly-exploited seas, animals they could never hope to catch via their own means. On which topic please don't allow cats to kill native wildlife, they are a human-introduced predator and as such occupy a potentially devastating place in ecosystems, especially given their vast numbers.
Neither belongs in a "petfood" can. |
Now onto diet, cats are often more finicky than dogs, and their nutritional requirements are more complicated however this shouldn't put you off transitioning a cat that lives with you to a vegan diet. Unlike dogs where switching food is a generally a relatively easy switch (being that most will eat anything!) changing a cat's diet is something that will likely simply take a bit more time and patience.
I would suggest start with the current food (this is for wet food) and add a small percentage of the new food and see how that goes (hopefully the cat wont notice the difference). Next day add slightly more and keep continuing until you're at 100% vegan food. This all assumes that you have no issues with the cat disliking the food. Should you get to a point (lets say for this example 50% of each) where the cat won't eat the food then there are a few good tips that I've been told. One is heating the wet food up very slightly (obviously please be careful!) this enhances the smell and can make the food seem more appealing.
Nutritionally there are a few things to look out for. Firstly cats need a considerable amount of dietary vitamin A as they cannot make their own (biosnythesise). It is important to ensure they have sufficient as without it they can get health issues including hearing,skin and intestinal issues. Another important nutrient for cats is taurine, again a diet lacking this can cause significant health issues. Both these and all essential nutrients can be found in vegan cat food and many cats have thrived on these. We have linked to both ready made wet cat food, kibble and Vegcat (a nutritional supplement to put in homemade food) at the bottom.
One of the most common health concerns with vegan cats is urinary tract infections. Because of anatomical differences, the risk of urinary tract problems is much lower in females than in males. Both genders can develop crystals in their bladders with females this may cause discomfort but the crystals do not cause blockage. This means that that urinary tract infections are much less severe in females than in males and are much easier to cure. In male cats however a blockage can occur and can be severe.
Females, as mentioned above, can usually be given a 100% vegan diet with no problem. And so can many males. However, we really need to stress that if you want to make your males completely vegan, you need to be very dedicated and vigilant when it comes to maintaining their urinary tract health. What does this practically mean? Well basically you should make sure you get your cats ph checked every 6 months (more so when you initially introduce them to a vegan diet). You can buy ph strips for cats online to do at home, they're easy to use and give you a quick indication as to whether your cats ph is fine (or not). Feline ph should be between 6.4 and 6.5, any higher or lower then make a vets appointment!
Next, NEVER feed a male (or female really but especially a male) a strictly kibble diet. Most vegan male cats will do best on NO kibble whatsoever. Cats usually get most of their fluid from their food, which is important for ph and flushes the urinary tract stopping minor infections. They will drink water but not enough to make up from not having water in their food. If they will only eat kibble then consider soaking it in water for a few minutes prior to soaking.
So experimentation is key. With so many permutations available you should be able through sensible, gradual analysis to find the ethically optimum diet for your cat. If you have tried everything you can and still can't get your cat to accept a fully vegan diet then it is better to have them on a percentage of vegan food like a 75% vegan wet food mix than a fully meat based diet. Try and get to as high a percentage of vegan food to animal-derived food to at least feel you are best reducing the suffering this one animal, you are responsible for is causing.
Finally, the other most important thing is to spay and neuter! We owe a great duty of care to the overflow of domesticated animals we have brought into being and should always vehemently oppose the wanton selfishness of breeding new ones into existence.
