I left the shelter on my patio after LBK was placed in her new home in case the other cats would come around. This morning I saw tiny paw prints in the snow but not to or from the shelter but from underneath my tarped patio furniture. The shelter has blankets in it and, until yesterday, a heating pad. It's covered w/a tarp to protect it from the wind and it's raised off the cold concrete. The tarped patio furniture is directly on the cold concrete and yet that's where the tracks led. Honestly, you'd think the cats would want to be where it's warm and snuggly, wouldn't you?
