My cat uses them everyday to stretch & claw!!

Of course they loved it

This is just what I was looking for. I use it for my Catio which has a big window on one side. The suctions work great, even when the cat totally puts all her weight on it. It did not come with a ball on it, it came with a cut out felt butterfly, but that was not a big deal for me. Nice space saver.

This is a great scratcher that will STAY PUT on the glass. The suction cups are huge and industrial feeling so I feel confident it won't come off over time and can handle my 2 cats using it.

I have a multi-cat home and only one of my kitties uses this scratcher, but that's enough to make this a worthy purchase. Minus one star because it only attaches to glass/windows when the description says any smooth wall or door.
