  1. Letting out all the heat! 2 Star Review

    Posted by on 30th Nov 2016

    I replaced the flap because my cats had pulled off the fringe and the door wouldn't close all the way on a consistent basis. New fringe and still no consistent closure on it's own. I have to get up and tap it with my foot nearly every time. So frustrated.

    The replacement pet door shipped quickly. It arrived in just a few days. It was easy to remove the old one and put the new one in. I have been so impressed with the quality of the Ideal pet window and to be able to replace a part, rather than buy a whole new unit, is so wonderful. This window/door is one of the best things I've ever purchased.

  5. Exactly what I needed 4 Star Review

    Posted by on 20th Apr 2016

    My original flap for my cat door was damaged. Being able to buy a replacement meant I can use the door exactly as it was intended. Although the replacement cost nearly as much as the whole door, I am glad to have it working and looking as it should. Thank you

    Easy replacement door. So excited this exists. Have had the hefty cat window "door" for several years and it was in rough shape. Perfect replacement.
