One of my three began refusing to come inside. As the weather turned cold I decided to take styrofoam cooler that came from Omaha Steaks a while back and make a shelter with a heating pad set on lowest setting, so he would have a source of shelter. Went to the door one night and a raccoon came running out of the shelter! The cat decided that very night to start com,ing in at night. Now he sleeps on my bed and as a big heat weight, he is becoming a nuisance ... but I love him and just move him away from m,y pillow.
Our kitteh tribe is strictly indoors. We’ve lost too many over the years to owls and coyotes. All three of them pile on the bed with us. We usually have to move them around to reclaim enough real estate for ourselves.
