I purchased this cat house two weeks ago and my cats have been trying it out since. First, the material seems very durable and so far it has remained waterproof. I like how easy it was to build and also how easy it is to take apart. This allows me to move the pet house around as often as I need to. I like that there is a little plastic door in the entrance because it allows my cats to stay warm when inside. This cat house was a total success for me and my cats. They have no problem going in there and love to hang out in there as well. I built a cat patio for them and this has been a great addition because it allows my cats to enjoy their patio even if the weather is not the greatest. I definitely recommend.
