Mice measure about 2.5 by 4 inches long. They are stuffed with 100% pure Canadian catnip for 100% cat fun.

Catnip is an herb. If it is left out for a long time it will lose some potency. To refreshen the mouse, mist it lightly with water; place it in a baggie; leave it on a sunny windowsill for a day or two. Your kitty will be thankful for your efforts!
