I've owned nine cats at various stages of my life, but unfortunately only one of them is still with me (two had to stay back in Cape Town with friends.)
I mostly wanted to say... cats that don't come when they're called? Good heavens! *All* my cats have come when they were called, and that includes the current one, who is a scaredy cat - his mother was feral.
And one of my cats used to come for walks, too, though she wouldn't let me leash her.
