I bought this kennel to bring my Maine Coon mix cat well to the vet. Before that I had only a small box, in which he almost did not fit in, and it was always an ordeal for him, as he could not move properly. However, the smaller box fits perfectly for my Siamese mix female cat. Can the box really only recommend it because you can take out all the grid also, therefore you get the cat well and out. The whole box can also be taken apart, which makes cleaning very relieved as opposed to the smaller box in which it is also an older model. The upper opening I also managed to make one thing can calm the cat by petting. Unfortunately, the hangover has pierced with his full strength, the upper flap, and now is a broken lock. Perhaps something should be improved in the stability and the material here. I'm going to simply replace a flap for the feed with the Streichelklappe. Otherwise, I certainly hope that you can reorder as a flap if necessary.
