I relate to this struggle so hard lol. I've got 3 cats, one of them for 10 years now and I'm still trying to figure him out.

The newest one, 2 years old, seems to consider moving water his greatest nemesis, so I've had to stick with the traditional bowl - I always go ceramic though. Less chance of toxins. I never touch plastic!

My current battle is with weight. One cat is skinny, one is fat, the other is just right. Dieting for one is impossible without starving the others as he'll eat theirs. Sigh. The only think I can think of is investing in one of those 'cat ID unlock'-type bowl systems but I'm not even convinced that'll do the trick as he meows like madness whenever he's not totally fed to satisfaction, and my wife works from home so... urrrrgh.

Always an adventure!
