If your walls are wider than 2" apart, you will need to buy one or more additional 2" pads for $11 each (cheat). Our interior walls are 5 inches wide. The magnet is too strong for shy cats and I think should be easy to remove for people using flaps between the inner walls. As is, the magnet is glued behind the plastic. Some people will have trouble removing the magnet. but I did it in less than two minutes == How to remove the magnet == Use a small _sharp_ wood chisel, a small hammer and a broad head screwdriver to pry it out of the white frame. break the glue. If needed I can glue it in place. "Damage" is not visible as this part is hidden in the wall. Despite these issues I have just ordered another valve + liner so we can have a cat valve from the inside to our sun room. Feels like a rip off for liners but I looked elsewhere and couldn't find anything cheaper than making my own liner out of wood (no thanks!)
