Provides good entertaining exercise (until she works out where the light comes from)
My cat loves chasing this and I shine it on her cat post as well as everywhere else so that she can have a good run round and also test her hunting skills (ideal for an indoor cat). The only problem was that after a couple of times playing with it she worked out where it was coming from, so I have to stop using it for a while before bringing it back out again. I also worry that I might get the light in her eye by accident. Apart from that it is definitely worth having as it is good value and you can bring it in and out of the cupboard whenever you want.
