I purchased the KatKabin about one month and half ago, and it's been in use for about a month. I live in Michigan, so we have not had any extreme weather conditions to speak of yet, and the Kabin has been protected on my porch the whole time. I noticed a couple of days ago that the plastic cracked on the outside, and there is no good reason for it. I'm using the winter warmer already, since we have had some cool nights, and I can see the warmer through the crack. I'm glad I had the warmer, or there would be nothing to stop cold air from entering in. I contacted the company and they are sending me a new outer panel. I have read that this happened to other people as well, so it's pretty disappointing consider how much it costs. The cat seems to really like it though, and beside the crack, everything has been great with it. I think the company needs to come up with a better plastic covering for it, since it should not have cracked like that.
