Snape won't quit biting my toes

Naming a pet, especially a rambunctious kitten, after a fictional character presents some highly amusing moments. Especially if said character happens to be a surly, glowering potions master.

The mental images are just hilarious.

For instance, praising Snape for finally figuring out the idea of the litter box, after the umpteen billionth time putting him in, praising him, and rubbing his feet in the sand.
