Great product! At first, the cat was a little nervous when Mojus moved, but after a few rounds, she started playing with him non-stop. An hour later he carried it by its tail into a large wooden floor room and played alone for half an hour. In "Paw" mode, the factory batteries will still work after 2 hours. I bought 20 as a backup but haven't had to change them yet. The toy has realistic zigzag patterns as it touches the edges and legs of the table and slides very well on the baseboard. This toy uses legs rather than wheels, so it works best on a hard surface. My cat is very attached to this toy. I bought it on sale for less than $15 and was a bit surprised that some people said it wasn't worth the money. I almost got a round ball, but the reviews said it couldn't see or avoid objects, it smashed right into everything, and every time it hit something the head fell off. 10 times more expensive than this toy. For money. This is a fun toy for any cat. It was way better than expected
