I have a stray cat that I've been taking care of for four months now. Winter is approaching. I've tried a box with blankets, a small dog house, tried my basement but he walks around and as soon as the door is shut, bolts upstairs and wants out. He will sleep in a chair outside with blankets and I have moved it to a corner on the deck where my husband put wood on the sides and put a roof over top. He goes somewhere late at night but I don't know where. I have no garage or shed. I worry about him when it will start to snow. He doesn't like to be inside or feeling like he's closed in. What can I do for him? Just let him go wherever he goes at night hoping he's warm? I don't know what else to do. I thought he might like the corner spot we built for him but maybe I should add straw? Does anyone have any other suggestions I can try for him? Thank you.
