ok, ok I did NOT mean to sound rude - just the thought of knowing wolves, coyotes and bears were known to be there and keeping a window open and I thought maybe it was a joke to start an inside/outside war

The enclosure sounds good, or keeping him on a harness when you can take him for outings? Maybe after awhile, if you know he is going to stay close the to house (hopefully) he can have freedom during parts of the day only? How about limiting his freedom to supervised sessions like maybe weekends only when more people are around to keep watch? Scheduled outings sort of?? I would really worry about the total freedon to come and go. Even kids get limits for safety.

My kitties are declawed and indoor only so I am really not much good for ideas, sorry
