kitty aggression

What I find truly amazing and annoying is the kitty aggression. Marley has been way more active lately than before. I'm hoping that some cold weather will chill him out. Last night as I sat on the couch and him on the floor, he was finding new and inventive ways to bite my hands. I literally watched his pupils go from normal to HUGE in like 2 seconds. Too bad my reflexes aren't that quick. He got me, got me good. Then he ran away. Little monster.
