Why did we make Glow Cats? We were thinking, how do you improve a cat? Impossible! We’ve tried by making them glow in the dark, but really they aren’t better, just different. This set of six differently posed kitties will glow in the dark. Perfect if your own cats have trouble finding things to knock off the shelf while you’re trying to sleep. Made of soft vinyl, all the cats are around an inch on their longest side.
