During the depression, hobos used to post signs to alert others that they could get food at this house, use the telephone, there was vicious dog, etc. So, my friends joke that there are secret signs posted on my house to alert any stray animals to come to my house.
I'll look out my window and see a stray dog or cat walking past. It's a thing. I once came home to find a lost homing pigeon on the porch. It lived about a block south.
So tonight, it's 11:30 and I hear a jingle in the back yard, turn on the light, and yep; there's a dog in the back yard. Fortunately, I recognized her and was able to get her back home, (she lives on the next street over and must have gotten out of her yard) because I don't think my dog would have allowed her in the house.
