A storm door with a pet door already installed, or an exterior door with a built in dog door is the perfect solution for people who don't care to cut a hole in their existing door.
NEW! We now offer standard size Glass Inserts with built-in pet doors that are designed to replace the existing glass insert in many standard exterior metal doors.
Glass Inserts with pet doors are easier to install than exterior or storm doors with pet doors...and they cost a lot less. If your current glass insert is secured with screws (not nails) then all it takes is unscrewing and removing it and installing the new glass insert.
