Review (3/5): Design could be better
I have three little kitty girls and they love to scrape against stuff. These are really cute, but they definitely have some design flaws. They do not stay on the wall very well, the stickers it came with aren't very sticky so I ended up using my own wall tape. The spiky part is hard plastic which is fine for my cars but hard for me to take apart to wash, fill with catnip and then put back together. I wish there was a bigger opening in the back to put in catnip.
