Unfortunately, we cannot recommend any solution for cat doors except to close them off and don't use them. Unless manufacturers develop a steel cat electronic door that only allows the collared cat in and actually stops the raccoon, we must give you the bad news. The present plastic doors are too weak to withstand a determined raccoon. Failure to heed our advice may result in raccoons entering your home and/or eating your pets food and exposing them to diseases. Fleas and Ticks are also a concern as they may fall off as the animals move around.
We would welcome learning about any product that works to keep out raccoons while allowing the movement of cats.
