Any suggestions on how to transition semi-feral from scratching outside wood (some tree logs used to partition off garden) to a scratching post? Totally not interested in a post. Also, I'm in the process of making an outside house out of bins. He hasn't been interested in other outdoor shelters for more than a few days, so any pointers on getting him to use the new shelter I'm building? There is a crawl space under house that I've left accessible for his safety which he does go into if feels threatened & might sleep there at night (not sure)--and wondering if I close it off whether he'd be more apt to use new house? I'm a little apprehensive about taking away his refuge?
