I had two feral kitties I was taking care of this past winter - a black female and a gold male. I built them winter shelters but black kitty was the only one that would use them. Gold kitty would not go in them and slept under the deck all winter. Black kitty disappeared a couple of months ago and I haven't seen her since. Gold kitty stayed all winter sleeping under the deck. Now that it is spring and getting a little warmer gold kitty decided it was time to sleep in his shelter about a week ago. Silly kitty lol
