Review on Pet Products Mount Scratcher Kitty by Sopheak Kupke

My cats love this cat sleeper. My cat is quite large and I was really impressed with the threshold's suction power. It holds up well and feels sturdy. The windowsill isn't big enough to fit more than one cat at a time (unless they're babies), but my two are definitely trying to push their limits. Even then it stays in place. The only design improvement I would suggest is a paper liner on the bottom to catch any cardboard shavings from using the window sill as a scratching post. I vacuum underneath regularly. I plan to buy another one of these so my kittens won't have to share.
