I would like to build a few cat houses for local feral cats to help during the winter and protect them from coyotes.
I was thinking of using about 1 inch hardwood plywood. What are some good joints to use that provides the best chances for the cat house standing up against a coyote? The cat house will have two levels which the upper level allow the cat to remain safely from jaws of the coyote.
If there are any other suggestions I would love to hear those too. Thanks.
