He is either guarding the garden or just sunning himself on the patio.
Unfortunately, he has been bringing wildlife into the house and it is not yet dead. So my pet had a pet (mouse) for a while. Finally it got so injured by being chased around over and under the furniture, that I was able to catch it* and put it outdoors. I wasn’t quite brave enough to put it out of its misery so I guess one of the neighborhood cats will do that for me.
*Initially there was this interesting scene where I was chasing the mouse to rescue it from Murphy when I realized that the mouse was just as scared of me as the cat. Also Murphy thought it was a great game!
