Trouble won't be a year old until July but he's 15 or 16 pounds now. He was the "monster" of four kittens and the most aggresive to catch a nipple and stay with his mother as a kitten.
Today? He's the nicest fellow you could meet. Even before he got neutered he was a gentle sweet cat. If you pet him he drops to the floor, closes his eyes, and makes joyous cat noises.
He can even roll up like a sleepy dog in my upstairs filthy man cave.
If you pet his head and stop he will find some way to get under your hand and nudge it with his head for more.
