As a renter I have always had to leave a door open so my cat and 2 cavaliers could come in and out as they pleased, but thanks to the temporary pet door those days are long gone. Delivery was super fast, I ordered late on a Tuesday night and it was on my doorstep Friday morning. As I am in Central West NSW I was expecting to wait at least a week so I was very happy. My dogs used it immediately and within 2 days my cat trusted it enough to start using it too. As we have just purchased an Amstaff puppy, the day will come when she wont fit through the medium door we purchased so it will be with no hesitation whatsoever that I will be returning to buy the large door. I recommend this door to every one of my pet owning friends as the are fantastic and look great too.
