Our boys LOVE the PetMate. Archy used to drink my little rock fountain almost dry, so the PM is a godsend. He had no trouble with it, but he's a very curious guy and unafraid.

You do have to make sure the little pump doesn't get clogged with pet hair. I use a toothbrush to gently clean it once a week.

Archy also uses it to 'wash' his pet mice and the pipe cleaners!
