I got him at 8 weeks old, and he's now almost 10 weeks. He's doing amazingly well with litter box training, considering he's not neutered yet (he will be at six months) and eats, drinks, and plays like a champ. I was worried when I first brought him home, because he barely moved, but that's gone now and his personality has really started shining through. Needy and bossy, if you were wondering.
He had his first excursion from the cage today and he loved it! Racing around the room and investigating everything.
