For the past week, Milo has been refusing to go outside to sleep when I tell him to. Normally when I say "bed time", he will stand up and walk to the door and wait for me to tuck him in bed. But lately he's been ignoring the command and running away when he knows it's time to sleep. I understand it's cold outside and a lot warmer inside.
His 'bed' is an old kitchen cabinet rotated so that the base of the cabinet is where he enters - like an open box. It's lined with carpet and about 5 old towels. I have noticed though, that despite it being all 'wooly' and full of cotton, the material is quite cold from the environmental temperature.
Sleeping inside doesn't seem to be an option since the rest of the family forbids him upstairs (even though I said I don't mind him sleeping in my room). Also, he can't be left alone downstairs as he'll look for us when he wakes up - so he'll end up going upstairs, AND he nibbles on our furniture every now and then when no one is watching him.
I would really like to find solutions for either:
1. getting Milo to just deal with it and sleep outside - stop being a sulk (what my family would like)
2. trusting him to not chew on furniture and not come upstairs if left alone to sleep.
EDIT: I would like to add, that the only room downstairs is the study room with a few electrical wires so he can't be left alone in there. He normally sleeps in there while I work, but he's never alone in there.
The rest of downstairs is completely open area, so isolating him downstairs will be difficult.
