Excellent product
My husband and I were new to cat flaps, we didnt have one for our previous cat who tended to spend most of the day out then in for the evening. But this kitten is in and out at regular intervals so we looked into a cat flap to give him the freedom. Would highly recommend, a joiner fitted it in approximately 20 minutes to our rear door, best decision we made, it took a couple of days of patience in training him, coaxing with toys and treats as he was nervous at first of the clicking sound.
