FYI I have no patience for non-vegans concern trolling vegan issues. If you're actively harming sentient animals, your opinion is clouded by your own guilt. Apologies in advance if you happen to be vegan.

So you’re saying that vegan cats had roughly the same health as non vegan cats

No. That is not what the study is saying. The study is saying that "we took a look, and couldn't tell if there was a difference or not."

I don't know why you're so concerned about my taking my ending summary, out of context, when I wrote paragraphs summarising the lit review and minor differences in kidney issues with non vegan vs vegan cats.

couldn't tell if there was a difference or not

Science doesn't speak in absolutes expect in maths. If you read anything outside of the abstract, you'd see that there's a few other existing studies that support it, no studies claim the opposite, and further research should be done as in all medical research of this type.

Other studies may very well have more rigorous methodologies

No kidding. No if only the "cats must eat meat" side had this sorta need for rigorous methodology.
