He has a large aluminum flat based bowl for water & I clean that often as he plays catch with his balls and gets dirt in his mouth. YUCK! PLUS the balls are YUCK also.
He also gets carrots/apple chunks in am.
The cats have 2 aluminum flat bottomed bowls, I clean them less often. No wet food. But small amts of tuna once in a while on a plastic lid.
I refresh their water daily.
Chance has a plastic water bowl. Cleaned every morning. He washes seeds, fruit and bathes in it. He has a seed bowl I put fruit on top of his seeds. Every morning I give his leftovers to the wild birds. And clean his bowl.
I have these steps memorized..along with cat box etc.
