Image deceptive it is not tall enough to cover an entire doorway if there is any adjacent climbable service your cats will be able to jump it because it does not go all the way to the top of the door frame. I had to add tension rods at the top. There is also a lot of plastic parts unlike smaller gates that is all metal and these plastic parts are what is the issue. The bars are metal but they are also not 1 entire piece, it is 2 poles that screw together with a plastic connector or the side bars attach with plastic connectors at the top and bottom a few of mine are now lose and no longer straight not matter how hard i screw them together. If you have kids that will easily wear out the bars at the connection joint and the will no longer stay straight and are expensive to replace.
