Mark named him Rocky.
The next morning I refilled his food and put him out on the porch. I thought I should let him go, so I lifted him up and put him on a planter. He ate some food, then fell asleep, right in an area frequented my cats! He was exhausted, so I picked him up and he decided to crawl inside the sleeve of my sweater:
Finally I pulled him out and decided it was not safe to leave him exposed like that.
I made a little cardboard house for him with a very soft blanket inside and a little baby-squirrel-sized door and I kept some water and peanuts next to it. Soon we discovered that Bullwinkle liked the nesting idea too:
The next thing I knew we had 4-5 tiny squirrels nesting in the box. I fed them for several days until they were strong enough to go out on their own, which they did. I still see them around sometimes, getting fatter by the week. Anyway, it was a fun distraction from other matters.
