My mom's cat is a butter fiend, and since my mom makes toast every morning, they've got a routine now. And if you don't give her any butter when you've got it out for toast, baked potatoes, whatever, it's your death knoll.

My current cat's morning routine is to run like an insane thing into the bathroom ahead of me, jump up on the counter, and wait for me to close the drain and run about an inch of water into the sink, so she can have the freshly-killed water instead of that horrid, poisonous stuff in her water bowl that I dare give to her.
