Review on Explore the Hooxincci Cat Window Perch: Best Wall Mount Cat Hammock for Indoor Cats, crafted with Durable Sturdy Bamboo, perfect for Window Sill Gaps by Jennifer Mulder

I have two older cats that like to sit near open windows. Due to the layout of our windows we needed one that could be easily removed and made for open windows which meant most perch options flew out the window. Of the few remaining options, this one seemed the most practical for our needs. As a minimum I would say you need about 0.5 inch. While this works great for my cats, there are a few minor annoyances to be aware of. While the board is solid, it already has a decent handful of dents. Also, the screw holes for the metal L-brackets were slightly crooked, I was able to straighten one side, but the other had to use a little more force to get it right. The kit is included, but a slightly larger screwdriver makes the task a lot easier. Also, due to the fact that it's removable, I recommend some of those cloth circle stickers you can put on wooden support pieces , It can slip a little if Your cat makes a big jump on or off it, possibly damaging the paintwork or scratching the wood it collided with.
