I'd have to put my vote with a dog. I had one before, Charley, Full Bred Rott, that dog was my best friend, would die protecting me. That dog got me soo many woman it was great. Gave many nights of wrestling, runs on the beach. A cat, I have one now, Laziest thing with 4 legs. Nowhere even close to replacing Charley. Charley was irreplaceable.
