What stops other animals from using a pet door?

A few things that may deter other animals from using a pet door include, but are not limited to:

  • Motion sensor lights above the door may deter nocturnal or skittish animals when they move in the sensor area and the lights turn on.
  • Pet doors with a key that your pet wears, or electronic pet doors, have become a popular option among pet owners. Your animal can wear the key on their collar somehow and that key is the only thing that will open the pet door. This way other animals can’t come in, and inside animals can’t leave.
  • Using a darker opaque barrier may deter unwelcome visitors. Other animals may not be inclined to push against a barrier they can’t see through. If a clear plastic flap is used, the outside animals are more likely to breach the pet door because they can see inside.
