Title: Good for indoor use
Review: Nice door for indoor use. The small size is larger than several other brands we looked at, with the U-shaped door providing more space than half-circle styles. I appreciate the 4-way lock. It doesn't seal well, so I wouldn't use it as a single flap on an outside door. We use two of them, one on a small cat house in the yard constructed over a basement window and the second through that basement window, forming a kind of airlock between the outdoors and our basement.
