I used to have a cat, born on the same day my son was. The cat was the runt of the litter, but mom was a siamese-something and dad was an actual wildcat (you know, big ears, big claws, etc.). the kitten was grey colored, so he got named Grey (yeah, I know, real original). He grew up to be a 27 pound monster. He loved people but hated every animal that walked, flew, slithered, or swam. I had a German Shepherd at the same time, right around 125 pounds, and the cat loved to get the dog to chase him. That way, the cat could judge his distance, do a mid-run pivot, and jump onto the dog's head. The fur flew, dog was looking for an exit, and the cat just strutted his stuff. I loved that cat.
