Welcome to PT! There is no higher honor in life than to be chosen by a cat to be their purrson. You are SO blessed!

It doesn't sound like Scooby's current mom really wants him (or the other cat - you did say there were two cats, right?) I'm sorry there's a child involved, but as others have stated, letting him visit sounds like a good arrangement if it works for you.

I do hope you decide to give Scooby the home he's decided to claim as his. Once again, welcome to PT and please more pics!
