Query: Perfect Pet says it all !!

This is the one if you have a large Cat or small dog, (like a pom) has LARGE opening...not like others on the market that just say they are large... it works great, easy to install, locks the animal in or out or unlocked both ways.. easy for pet to open..my Puss just loves it. We are using it on an air conditioned bedroom...fantastic !!
