Pros-

This is a great product for the active cat.

Cons-
At three in the morning it's pretty startling.
Kick it at three in the morning, It's pretty startling
Kick it when you are walking around, It's pretty startling.
Make a noise or drop something around it, It's pretty startling.
It makes a funny noise and the evil laughter at the end of the cycle
is pretty startling.
Is you are jumpy, it's pretty startling.


I highly recommend this toy for some cats and ALL cat owners.
