What do your cat/s do that surprise you?  

I have two cats. One night I was on the couch and one of the cats was curled up next to me. the other was pacing in front of the couch and meowing. Non stop. I couldn't figure out what he wanted. Maybe he just needed a little attention. So I reached down to pet his head. When I reached forward, I disturbed the cat curled up next to me. He got up and jumped off the couch. the minute I sit back, the one that was pacing jumps up on the couch and take the same position the other cat was in. I just laughed. Surely he planned that whole thing.
