We have an orange Tabby who adopted us by coming in through the dog door despite our German Shepherd (we have 2 other indoor cats so the dog just ignored the new one.) However we have been keeping the dog door closed as we were afraid he would go out the same way. The collar has worked great and now Tabby stays away from the dog door. My mistake was I set the collar for the highest level and saw him get shocked once. He went about 2 feet in the air before he ran. Now at level 2. Now the cat stays away from the dog door and the adjustment on the control box is great. It is next to the dog door set to 2 feet which is about all we need.
