We had a non-electronic door before and our neighbors outdoor cats kept coming into our home. Often we find them laying about on our furniture in the mornings. I called Moore Pet Supplies to see if there was a way I could control what cats were coming in, and they recommended several electronic doors. Being that I didn't want to spend hundreds of dollars on a door for my cats, I opted for this staywell door, and it works great. my cats still use the door as usual and the neighbors cats have stopped coming into my house.
