Perfect. Ideal size for animals. It works properly.

We have several cats, various ages and personalities, one is overweight and it is hard to keep her moving. This mouse is perfect for the youngest to the oldest and even has her chasing it. It does not work on a rug but place it on a hard floor and stand back! Keeps them busy and out of trouble!

My cats can't get enough of this toy. This is a great way to wear out active cats. It works on vinyl flooring, but not carpet. They played with it so much that it ran out of batteries.

My cat is obsessed. She loves this thing and will chase it around. For such a low price, I was really shocked how well it worked and how it was able to turn itself around, most of the time, after bumping into things. It's very cute,

This has been one of the best toys I have bought for my cat. She loves mice so much I have been buying little stuffed mice, however, this one has proved her favorite by far.

It is cute! This little mouse is energetic and my cats love to play with it. My other cat is smart enough to realize it is not real...no smell, no tracks but she kicks it away when it comes near her. The male cat took a fancy to it and he chases after it and bites its tail or toss it around.

Our cat loves it! The button makes it really confusing to know what mode it's in, but in the end, it works out well. The movements are really good, the pauses really get the cat's curiosity.

My sister's Chinese crested dog will not play with anything! Got her this for Christmas,, she barks and grabs the tail, runs all overplaying! She used so hard had to get her another one!

This is my dachshund's new favorite toy! I think cats would really like it too. We had no idea our 6-year-old weenie could move like she did when we broke this new toy out. It's great exercise and very noisy entertainment for the whole family (she barks like crazy while chasing it).

I've had this for several weeks now and it is still working. I have scared the crap out of so many people. I've got to admit this is a great little gag gift to get especially if you're like me and enjoy playing tricks on people
