Not at all durable
I have two small kittens, weighing about 2 pounds each - and they had this destroyed within 24 hours. The frame snapped and poked out of the fabric, collapsing entirely. Total waste of money and I was very disappointed with it.
I have purchased 3 and all 3 ended up the same way, with the wire ending up sticking out of the corners, quailty needs to be increased
