I was told by the SPCA adoption center to wait until Buddy has fully adapted to his new home, and bonded with me, before introducing him to the outdoors. I did not receive this advice til recently, and had already taken him outside to the foyer, which put him into a panic. Apparently after thinking about it awhile, he has decided the outside is not so bad. When I open the door for fifteen minutes (with the floor fan in it) to cool the place off before bed, he tries to slip out. I now have to sit in front of the fan to stop Houdini from escaping. So how do I tell when 'Buddy has fully adapted to his new home, and bonded with me'? I'd like to have him used to the outside (and riding in the stroller) in time for the vet appointment in April, but don't want to rush it.
