Query: kitty door

I was not sure this product would work for me or not--it is VERY high quality--excellent weather seal--EASY instillation--a dog could be trained to use this in 5 minutes--for my cats, it was a longer process. Now after two weeks the cats come and go as they please--I sress again about the durability and quality of the product. Very attractive--looks like it is part of the door--the weather seal is working good here in North Texas with temps in the 101 to 107 degree range. This is the best price and free shipping of all the pet doors I researched--
