When I was growing up I had four cats that came to us as strays. Fluffy, Chunkman (yes, that was what we called him), Lady and Rusty. All of them were pretty smart and none of them I think would have ever tried this. Lady was the only one who didn't seem to mind water and would drink from the faucet in the bathroom.

Kitten vs. water balloons, what could possibly go wrong here. Cats love water right?! lol Those sharp teeth and claws won't do anything to those balloons!
