Bless their little heat-seeking kitty souls.
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.
