I also prefer dogs to cats, but have had a myriad of cats along with my dogs...my last cat, a big old Himalayan, acted more like a dog tho...he loved to ride in cars(which most cats dont like), he rolled over to have his belly scratched, he came when you called his name, and he seemed to prefer to have me feed him his special kitty treats one a time, like one might do with a dog..we just figured he was a dog, wearing a big fluffy kitty costume...
Sounds like an unusually mellow cat. I've had affectionate cats, but they were very selectively affectionate
