This door took me a whole 3 minutes to install, it is very simple and self explanatory, also the pets seemed to learn of a new escape in no time at all.

My little Yorkie would constantly scratch at the door to get let in. This wasnt such a big deal during the winter, but when summer rolled around and we wanted have the patio door open and the screen door closed, he clawed himself a nice little hole where he started letting himself in and out. We decided to re-screen the door and got the pet flap to aleveate the problem of him scratching to get in. He loves the door and uses it all the time. Thanks
