Cat doors give you and your cat more freedom and independence. With a little do-it-yourself experience, cat doors are easy to install in most standard doors. Electronic and magnetic pet doors give you the flexibility to allow access to certain pets. The key worn on your pet's collar lets you keep your cat in and let the dog out or vice versa.
These doors are designed just for cats, with wider frames and hard flaps. Hard cat flaps are easier for cats to push through and don’t drag along their backs like soft flaps. Cats also have proportionally wider bodies than dogs, so cat doors are designed to be wider and more square.
