I purchased this for the feral cat we have been taking care of. The mat was kind of thin and she chewed it up pretty much right away. The plastic is rather thin and the door won't work after I stuff it full of straw to keep her warm in the winter. Other than that, it works for what is intended for. She sleeps in it.

Pros: Has held up through the winters in NY
Cons: Doesn't keep the cat warm unless it's stuffed with straw and then the door will not work correctly
