Catwalk Superior pet doors have been designed to be maintenance free by eliminating problems often associated with pet doors such as broken flaps, broken opening and closing systems, noise and seal damage by pets, rusting screws and difficulties with large cats.
To overcome these problems the cat flaps are made from high impact Polycarbonate (Makrolon) plastic from Bayer of Germany, a world leader in plastic technology. This high impact plastic is also used in the manufacture of bulletproof vests and aircraft windows
Catwalk cat doors are available to install in doors, glass or thin panel doors. A magnetic version is available for each. These only let your cat in. Keeps strays out.
