In addition to our 4 cats who use the cat door on the side of the house, we have a feral one.  He’s not very sociable, but he likes to come in to eat and rest. He hasn’t figured out how to use the cat door yet, so we bought one of these houses for him. We weren’t sure if he’d discovered it (it took over a week) 1986 and today, my husband took this pic of him.  We are so glad we got this house for him, and he’s using it, because we get very cold temperatures, ice, and snow. It was easy to put together, and yes, it doesn’t feel as warm as we think it should, but it’s perfect for them.  We highly recommend it!!
