What funny, eccentric things do your cats do?

Cats are one of my favorite creatures, mainly because there is so much potential for amusement and variation in behavior. They’re so odd and particular sometimes and I love hearing about animals’ personalities and what makes them unique.

For example, I keep finding these toy mice sopping wet in the kitchen. I thought my roommate had gotten them wet or something, until just now, when I found one right next to the big water bowl for all the animals. Knowing both cats, I know they’re tossing it in the bowl and fishing it out for kicks.

So.. what kinds of weird, interesting, and/or amusing things do your cats do?
