Stranger in the house?

Just a short time ago my food source left me alone for a little while then came back with lots of sacks full of stuff the he calls food. He was moving some more stuff that was outside the door and suddenly this strange looking thing came in the house. It appeared to be an odd looking cat but it did not smell right to me. We sniffed noses and I followed it around to make sure that it did not try to stay or do anything in my litter box or eat my food. Then while I was following it the thing barked at me, then ran out the door.

The weather has been great and the food source has been letting me stay out until he goes to sleep. I can lay under the picnic table or on it if I want. There is also a walkway just inside the force field that lets me see everything going on. There is a tree or big bush just past the force field where some noisy birds have a nest. The birds go crazy every time I am on the walkway even though I cannot get through the force field to get close to the nest.

Hobo's food source here, I see Hobo was talking about when I was bringing in the groceries and a friend helped carry in some of it. She was out with her Saint Bernard and Chihuahua and the Chihuahua was the strange "cat" the Hobo met. Hobo was actually bigger than the Chihuahua aka Peanut. Hobo could not decide what to do with Peanut, whether to growl and hiss at him or ignore him.
