When I was a junior officer, we had a tuxedo cat and a Goldie-German Shepard mix. The cat would come up to the dog and love on him for a few minutes, once the dogs guard was down, he’d attack.
The same cat would come up to us and demand we pet him, once we satisfied his needs, he’d nip at our hands to signal that he was done with us.
I loved him and miss him and that dog terribly, but that cat was a real a—hole.
