I have had several cats that were so attached their behavior seemed dog like. Used to have a female that fetched and jumped up into my arms on command. I currently have two "puppy" cats (both boys) that come when called and follow me around the house. One of them always asks to be picked up by getting up on his hind legs and putting front legs up on my thigh just like a small breed dog. He does not extend his claws at all when doing this so he is not marking me like a cat tree. He literally wants to be picked up. Often if I am near the ottoman he will jump up on that and then up on me wanting to be picked up and carried around. The other one will growl like a dog if he hears a strange noise outside.
