That's funny you should say that. When I got that "Hi Mountain" kit about 5 years ago, I ordered 2 of them to save money on shipping (per kit).
I only used the one, and at the time our Kitty "Smokey" was jumping up on top of my Gun Cabinet pretty regular. Then he'd go back to the back corner, so I couldn't reach him, to get him down. I then set things around the edge of the gun cabinet to block him, and the small UPS box with the other kit in it is still up there, blocking the left side. Mrs Bear asked if it would be any good yet after all this time. I said I doubt it, because I didn't like it when it was fresh.
