Sometimes, Pets need a patio pet door. A Door thats dedicated just to them and one that will not get damaged from constant use. While you can use new petscreen products in your screen door, you cant make the screen door as strong as a purpose built pet door. A screen door is not meant to stop a speeding rottweiler going after a squirrel.
A good pet door will fit right into an existing patio door and still allow the patio door to operate normally so that us humans can use it. The pet door also allows the advantage that it can be removed easily if you have to move to new house with a new patio door. Some of the pet doors available today are very sophisticated. Some even have electronics built into them to open them when your pet approaches. They are even smart enough not to open for other dogs and cats and critters that you do not want in your home.
