It's amazing how cats can communicate so effectively with us humans. My CH kitty Diva tips over when she uses the litter box and often has accidents, so she has learned to use whatever litter box is in the room one of us is in, and will scratch or meow for help. She also asks to be picked up. And if she's in the kitchen and doesn't feel like stumbling to the living room, she'll holler until someone comes and gets her!
