My indoor cat even enjoys this product! I received as incentive for a review. I am going to be putting it outside hoping to become shelter for outdoor strays! We have a large wooded lot with a variety of wildlife so I am hoping no other creatures decide to make it their home. It stays warm and seems comfortable. There are two doors which makes it nice so a cat can escape out the back if needed. There is enough room for more than one animal. I may have to buy another for my indoor cat because she likes it so much! Product is made well and material is quality. I recommend this product for indoor and outdoor use! Cat lovers especially if you are like me and want to provide shelter for strays.
