Not that this is a bad thing, but Leo has lately become my little shadow. He has always been aloof and would allow you to pet him and accept treats like he was doing you a favor. Ever since the vet trip he has been such a sweetie! He sits in my lap or in the chair next to me and even allows me to pick him up for a cuddle. Yesterday he took my fingers between his paws and laid his head on them. He sleeps at the foot of by bed and sits in the window waiting for me when I leave the house. He is like a new kitty. He's never been exactly unfriendly, but even comes out and lets complete strangers (to him) pet him. He has started playing more gently with the smaller cats.(He's HUGE.) I wish I knew what happened, I would make sure to keep it up! I'm so happy with my big snugglepuss!
