PETKARAY 23.5" Window Scratching Post for Indoor Cats, Wooden Window Perch Climber, Window Mount Cat Scratcher with Suction Cups

The suction cups are extremely weak, doesnt matter on what surface (glass, drywall, wood). Very disappointing as the actual scratch-post is decent. Will be returning, buyer beware

I'll start out by telling you to ensure a tight suction. I can't stress that enough. Mine initially fell twice after hanging it, BUT, the seller immediately and personally contacted me to provide tips to firmly suction it to my glass door. With a suction bed situated directly below the post, adhesion is of the utmost importance and safety. Also, I have mine horizontal, not vertical. Bryan loves it. LOVES it! I sprinkle catnip across the top and he gets so excited using it before/after naps and when other pets pass by the doors. I'm contemplating a second for the bedroom, or suction steps. I just get scared of him slipping with such small steps lol. My opinion, big buy here! I struggle finding good, quality toys and products Bryan enjoys using more than a handful of times. I'm 100% sold on this space saving scratching post, and you should definitely give it a shot. The pricing is on point and the durability is great!

Bought the scratching post rather than the platforms in hopes of deterring a cat from our blinds. One of the suction cups was a little flattened, but would develop grip on the window after a few hours. I left the various fasteners loose so that there was some flexibility in the brackets, but that rattles against the glass and probably will have to be tightened. Our lightest cat (~9-10 pounds) will stretch up and use the scratching post, and the suction cups have held for about a week. Unfortunately, it's a larger cat that I was hoping would use it instead of the blinds. I may lower it about six inches to see if that is more appealing to her. Definitely measure your window before settling on it, because it is larger than I expected. The wood brackets assembled easily enough and feel secure. The nuts that hold them to the scratching post and to the suction cups are adjustable. I had initially thought about installing it horizontally instead of vertically, but didn't try that yet. If your cat decides to use the scratching post instead of your curtains or blinds, that's probably a pretty good value over replacing blinds every year. Unfortunately, cats are unpredictable, so good luck.

Sadly there were screws missing and one of the wooden pieces was split right where the screws would go. Disappointing because engineering with wood structure would tell you that’s not the proper placement of structural support of those screws.
