Everything is a toy to a kitten or to some cats. My two kittens will play with anything they can get their paws on. I have to act like I'm living with permanent toddlers and baby proof my home. I keep all twist ties, rubber bands, pens and other odds and ends in a drawer so they can't get to them. My kittens also love to play in the bathtub with or without their cat toys. Enjoy Proton while he's a kitten. They grow up so fast.
