Other commercially available cat flaps are usually very small in scale and the cats have to squeeze through and more often become stressed or panic here, not only that they have half their fur sticking to the upper or lower sides. Not so with this one, it a nice size, a normal-sized cat can comfortably go through, however, the cat must be something sent, because the door is heavier than the small flap and the magnet attracts strong, that is, they need to learn with paws, or to press both at the same head at the bottom so that the door also rises that goes harder than other valves. Our cat is Freigängerin for 4 years, has two days until she had used the rhyme out properly. Now there is no problem and she is much less stressful and much more often than in the past through the door, she uses them probably more because it is now no longer so closely. I can recommend them to anyone who has a reasonably clever animal home. It is provided with tunnel and fits in doors and windows, highly variable. Drafts I've absolutely no feel, a perfect seal. Absolute buy recommendation.
