She meant the diet that we have the most empirical evidence doesn’t harm/kill them.
We don’t have empirical evidence of the same happening with meat-based diets.
Do we have empirical evidence that a specific meat-based food is consistently safe over many years? My understanding is that many change constantly.
So modern nutritionally complete meat-based diets presently have a 100%-wont-cause-major-adverse-health-outcomes rate. Is this not what the studies seem to show?
Best we can do is what AAFCO and FDA already do. AAFCO sets nutritional guidelines and ingredient requirements. FDA regulates the safety.
We have some empirical evidence that vegan diets appear to quckly give cats major bad health outcomes without supplementation? The first comment in this thread by Elizabeth pointed this out.
Why is that diet representative of for example nutritionally complete Ami, which has been around for years? Isn’t it much better to just defer to AAFCO’s and FDA’s standards, which Ami meets?
The most parsimonious explanation is that the lack of supplements was the problem, not the “vegan”-ness. If I get sick from my potato chip diet, it doesn’t mean I should avoid a plant-based diet with all required nutrients.
If you were to consider all possible meals a cat could reaonably be fed today. On average, it seems reasonable to suspect that they would be healthier if more of those meals were meat-based than plant-based.
Based on what? I don’t intuit this at all. Furthermore, we’re not saying any plant ingredients. We’re saying the ones that meet nutritional, toxicity, and digestibility requirements for cats.
Both you and Elizabeth have offered something fairly distinct from AAFCO’s/FDA’s standards. And so far, I’m finding neither to be better.
Given how nascent the field is and how we’re only just finding out what supplementation we might have to give cats
It’s not nascent. AAFCO has been providing guidance on the nutritional requirements for cats for decades.
For me: I agreed with you and felt like my mind was being changed to being pro-vegan-cat—until I read Elizabeth’s comment pointed out the issues in the study. So for me it is mostly because you haven’t engaged with that specific comment and pointed out why the concerns that are highlighted in her screenshots (from the actual study!) are not something that I need to worry about.
Convince Elizabeth and you, by proxy, convince me I’m pretty sure.
The most parsimonious explanation is that the lack of supplements was the problem, not the “vegan”-ness.
Sounds reasonable to me. I didn’t say that a lack of supplementation wouldn’t solve it. I argued that meat would. Arguing for X doesn’t mean I argued for ~Y.
The study came out January of this year. That’s pretty recent.
Does a nutritionally complete vegan cat food exist yet that takes everything learnt from this study and all the studies it references into account without need for additional supplementation? If yes, I’d want to see a study where cats are fed it first before I place my own cats exclusively on it. Till then I’d probably be too paranoid to feed them a fully vegan diet.

I’m confused. By “that diet” you mean to say the diet that was tested in the actual study you use as support for your claims should not be taken as an example of something nutritionally complete?
Ok, after trying to figure out what “Ami” was I see in your post you refer to it as vegan cat food that exists on the market.
Apparently it has also been around for 20 years after a quick Google search. Now I’m just hyper-confused why Ami wasn’t used in the Domínguez-Oliva et al. Study instead.
Thanks Cornelis, I sincerely appreciate the good will shown.

I conceded on Domínguez-Oliva et al., and Elizabeth’s concerns were entirely valid. However, it’s one study and one diet, and I felt that Elizabeth was ignoring the basis of nutrition and biochemistry that I emphasized throughout the post. Thanks for highlighting that the food was lacking necessary, known supplements. That was a key point that would have been helpful to broach earlier.
A RCT study will likely be just a formality for something like the Ami vegan cat food. And yes, it’s frustrating that this hasn’t been done/published yet! As I understand from Andrew Knight, there’s a better study coming out this year.

I haven’t found Elizabeth willing to falsify their thinking as much as you and perceive general antagonism and defensiveness.

Not really. Check out the recall withdrawals over the year: https://www.fda.gov/animal-veterinary/safety-health/recalls-withdrawals
