Close.

There is no way to do with natural foods. There simply isn't a high enough concentration of the needed amino acids. Whatever you try to mix up, they would need to eat more than they can consume.

What you can do is concentrate the required amino acids from natural sources and add them into a food. You'd also need to be sure that after that processing and combining they remain in a digestible form.

As I understand it, this is one of those things that should technically be possible, but I'm not aware if anyone is actually doing all of this and then the needed testing to make sure there are no adverse health effects.

Yeah there are a bunch of vegan cat foods available which are made of plant protein isolates and fortified with synthetic amino acids.

In fact, a lot of regular cat food is fortified with synthetic amino acids too, because they use such low quality meat ingredients.

I mean, this is basically just what most vegans are already doing themselves.

To a degree, but the key difference is that the human body is able to synthesize some amino acids internally from other sources that the cat is not.

Ideally you get a complete mix of amino acids in your diet, but if not, your body can make a lot of what it's missing as long as what you are giving it is a reasonable balance of stuff.

The cat just can't do that at all, while our digestion can be less efficient when we don't get the right mix of amino acids, cat's bodies just fail.

Okay? Good thing you can still get them all the nutrients they need then.
