2 reviews forTIAKI Electronic Play Mouse for Cats

I have two cats, so I bought two electronic mice. The batteries that were included in the price are either dead in both, or there’s something else wrong. After just three days, both of them only roll a few centimetres. The cats play with them, but nothing really happens. I’ll try with new batteries. If that’s the issue, the product shouldn’t be advertised as including batteries.
