January 3: It's cold outside and Leo has not come home

Leo went out this morning, as usual, and has his heated hut on our back porch that he an go to any time he needs to get warm. If he does not spend a significant amount of time outside each day, he pees in our house.  He has not come home tonight (it's now 9:30 p.m.) and we usually find him on the back porch each day in late afternoon or early evening. We're wondering if someone let him in their house thinking that he did not have a place to go and wanting to be nice to him.  We can assure you that we have safe, warm provisions for Leo at our house and we are there each day to let him inside for the night. If you have Leo inside your house, please let him out so he can go home.  Thanks!
