It changes colors and bounces around as your dog chases it. It goes for quite a while.

My dog loves this toy! He is definitely entertained by it and hasn't been able to tear it up yet surprisingly. It lights up and you can play sounds through it too. It was funny watching my dog's reaction to the sounds we had it make like an owl hooting. Great interactive toy!

This could easily have been a 5-star review if there were an on/off button on the outside of the toy. Having to take the toy apart just to turn it on or off and change the different modes is extremely inconvenient. Other than that, my 3-month-old puppy absolutely loved it, and so did my 8-week-old kitten! They both had a great time playing with it.

Clearly not for large dogs. I read that in the instruction booklet. My cat swatted at it a bit then ignored it. I hope it grows on him. Sugar would destroy it in a couple bites. Sigh
