As I'm sure most of you have read that Sailor Jerry is a cat we found in out back yard and have been caring for. He comes in sometimes but isn't comfortable staying the entire night. For christmas I wanted to make him a heated bed. My grandmother had a beloved calico named Eppy who passed away some years ago but my grandmother kept her enclosed litter box. She, my fiancee and I cleaned it all up with this stuff that is supposed to kill the scent of previous owners and I brought it home, then I sewed a big comfy bed to put inside that has a pocket in the bottom where you can put handwarmers from walmart. I put one in and it made the entire thing really cozy. He didn't go in, instead he slept on the patio chair again. I tried putting some of his blankets in there, nothing- treats? nope still ignores the box. I knew this would be difficult because he doesn't like small enclosed places and I'm sure someone has probably tried to live trap him in the past so I was curious- any advice?
