Tajjy used to have those noxious poo's. OMG.
Gaines is physiologically more well-adjusted than any cat I've ever known. Never sick, poo always nice and solid. I've seen him almost barf like once. He eats and drinks the same as all my cats did...but he's just got a strong constitution. I think it's 'cause he's Russian.
Psychologically, he's a nut, but that's what I like in a cat.
