The kitties love these "mice." The tails don't last long so I guess it's good they come in a pack of 3. I also needed the actual wand part because the other one was really chewed up. They enjoy these even if i wave them around by hand. The panic mouse doesn't hold their interest for very long so it's nice to be able to manually engage them by taking the wand off. if you don't own a panic mouse your cats can still enjoy these.
