Tips and Warnings


  • Cats are curious; they are likely to use it anyway.
  • Place a two-sided sticky tape on the inside of the doggie door frame, creating an elastic connection around the entire frame. This will make your patio dog door impossible for cats to open. The cat may try climbing or jumping at it but will quickly be discouraged when they are unable to succeed.
  • Place knee high rubber boots with nails poking out of them next to your patio pet door to further prevent any cats from coming through this entrance point.
  • A good deterrent is using a motion detector that sprays water or blasts air whenever something moves by it. You can have one installed onto the dog door frame, which detects whenever there is movement.
  • If you have a dog door installed on glass doors, it is possible to replace the glass with something cats can not see through.


  • Do not install a motion detector that blasts air or sprays water whenever something moves by it if you have small children, pets, or older people around. It may cause injury and discomfort to them.
  • When installing peephole security mirror film, follow the specific instructions for the type of glass you have in your patio sliding door before applying it. Misapplying with this type of film can lead to cracking and breaking. If you do not feel confident enough, there is no shame in calling a professional with experience.

We hope you have learned how to keep cat from using dog door. Cats are predators, which means they are equipped to hunt. Cats will use their claws and teeth to attack prey by tripping them up, holding them down with their paws, then making the kill with their sharp teeth. It’s instinctive for cats to want to capture something moving so they can “play” with it until it dies. Dogs are not predators whose primary hunting mode is pouncing on suddenly caught prey.
