Yeah, so something you should know about vegan cat food, is that none of them properly fulfill all the cats needs. They can claim it, and they can potentially even keep a cat alive and mostly nutritionally balanced, but it varies from cat to cat, and food to food.

And honestly, they are obligate carnivores. Just because you might be able to safely feed certain cats vegan foods, doesn’t mean that they should be.

And no, cats that eat vegan are absolutely not going to have equivalent or better health results. You’re literally feeding them things they weren’t designed to eat.

I don't have time to look up the studies that have been done on it, but you're just not correct. In the studies I've seen they tend to have equivalent or better health outcomes. If you find research that says otherwise I'm open to reading it, but just your intuition that feeding them things they wouldn't eat in the wild means they can't be healthy doesn't cut it for me

The studies you’re talking about were small, and typically self reported by the pet owners. If they were a human study they wouldn’t be enough to go off of.

Best research paper out there is actually looking at the studies in question, and isn’t specifically for cats but pets in general: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9860667/

And it explicitly states that much of the data was gathered through survey, not a controlled study.

Imagine if we decided that ice cream for breakfast was healthy because we sent out a bunch of surveys and people said they saw health benefits.

"However, there is little evidence of adverse effects arising in dogs and cats on vegan diets. In addition, some of the evidence on adverse health impacts is contradicted in other studies. Additionally, there is some evidence of benefits, particularly arising from guardians’ perceptions of the diets. Given the lack of large population-based studies, a cautious approach is recommended. If guardians wish to implement a vegan diet, it is recommended that commercial foods are used."

Thanks for linking the review! Of course more and better research is needed, but a cautious approach like they recommend makes sense to me. If you feed a cat a vegan diet, you need to monitor their urine for crystals (there are special litters that do this, or stuff you can put on their regular litter), and you should know you can't switch them overnight. But it is possible for cats to be healthy and happy on a vegan diet.

Your intuition that vegan cat food is as healthy for cats as ice cream sandwiches are to humans is not enough, and when you look at the nutrition content it doesn't even make sense. An ice cream sandwich with all the necessary micro- and macro- nutrients a human needs to thrive would be a better comparison, and guess what, a nutritionally complete ice cream sandwich would be fine! I've gone for long stretches where I eat nothing but meal replacement shakes like plenny and huel because I'm lazy, and it's fine. You can find at least one person on reddit who's done it very strictly for years with no problems.

if you're going to fight this battle, you also need to fight it against non-vegan cat kibbles, many of which are worse for cats (i.e. less nutritionally complete) than vegan kibbles like benevo or evolution
