Maybe I will build a large covered pen outside the window - so he can still go outside but nothing can get to him. Perhaps I can build it in such a way as to include a tree for him to climb. I really can't see forcing him to stay indoors all day when he loves the outdoors so much. He generally does stay quite close to the house.

And no - this thread wasn't a joke! I will allow my children and stepgrandchildren to play outside. (believe it or not, people on farms do allow their children outdoors) I'm not going to keep them locked in all day and I will not do it to Toby either.

He's an individual, not a possession, and I will do everything I can to help him to SAFELY maintain as much independence as he can. I'm not going to lock him inside the house like a bird in a cage.

I was asking you for creative options to keep him safe and help him maintain more freedom in his new environment.
