Got this as a gift for our backyard visitors ( 2 strays), they were scared to go in at first, and one of them finally made the move and they have been coming back to it almost every night, I also got the A framed one, they seem to like to go into one together tho, they like the a frame one during the daytime and this one at night (this is pretty tight space for two cats to be honest) , I do not understand why but as long as they are safe and sound in them. The pad cover is washable so I have washed them couple times already. I am hoping that this winter won’t be cold for them anymore.
