Yeah, my cat is always very talkative at night, right as I'm trying to sleep. He does this thing where he tears down the hall and sprints down the stairs. Then turns around and runs back up. Over and over again until I get mad and shut him in the laundry room.
Bad kitty!
Yup, mine also is very quiet when I turn in for bed. Then 10 minutes later, just as the sandman comes, so does the cat! Zipzat, meow this, toss the ball into that.
