His house looks nice and cozy, looks like a nice little den in there for him. I'm very glad to see that, and not the box

Do your parents have different plans for him in the wintertime? It still will get terribly cold and I worry about him being lonely a lot in the winter, I know it gets so cold in MN that I spend very little time outside. I still very much hope they let him come in at least like a garage/basement/shed then.

It looks like you are doing a lot to take good care of him though
