I adopted him (about this time) 3 years ago. We had snow, freezing rain & sub-twenty temps. His (original) owner left him outside.
Me...being Me....couldn't stand it, so I started letting him in. He got along well with Tug & Harley. In fact...he made himself right at home.
Then...about a year & a half ago...he started spraying/peeing in the v-man's room. Big mistake. I won't tolerate that nonsense....so out he went. Don't worry though...another neighbor started caring for him.
Imagine my surprise...when I found him scratching on my door at 6:00 a.m. the other morning. It was freezing out...and snowing! (fucking part-time pet owners)
So... I let him in. Been here since Saturday morning... ...making himself right at home.
