Love this! I have 3 for the Bootsies Cat bunks and 2 of these roofs. My cats use them every day. I just wish that there was an option to buy the bunk and roof pkg.
Both of my roofs are secure and haven't fallen or been knocked off and I have 3 active SiemeseX's (ages 3, 2 and 9 months). One of these is located at the foot of my antique bed (it high of the ground) and the kitties use this to get on and off the bed all night long, and no Sound issues at all! Beyond sharping their claws (which as a life long cat owner is white noise to me) and them squabbling over who gets the peak of the roof where two of the like to perch (again,which as a life long cat owner is white noise to me, not unless it gets heated). I haven't had to do any altering or adapting to either of my roofs. The other is located in my spare bedroom under the window, and they use this to jump to and from the window perch all day long, and no issues at all.
Do note that the Bunk that does not have a roof is under an end table.
