Just remember to watch out for playful kittens, too, guys.
Remember the story of the guy called out of the shower by his wife to fix the sink?
Kneeling, naked, dripping wet, head under the sink, when the playful little critter sees something to play with... with it's very sharp little claws...
He got clawed, hit his head under the sink, and woke up to his wife and two paramedics trying to keep from laughing... oh, the humanity...
