I have had two cat enclosures: one built by another firm and one built by CatPad. The CatPad enclosure is, no joke, about 4 times better than the competitor‘s enclosure. It is more secure, more robust, more convenient to use, and more professionally finished. And it cost about 1/2 the price. The CatPad people were also a pleasure to deal with. I can’t recommend CatPad highly enough. Don’t waste your time going elsewhere: go straight to CatPad.
