An improvement on the original with knitted-in eyes and ears.

Designed by Robert Matthews, with slight modifications by Esther Smith Bozak and further modified with knitted-in eyes and ears by Iva Maclennan.

The original, unembellished version is Catnip Mouse Toy.

You will need only a small amount of yarn, around 1/2 ounce or so. Use needles several sizes smaller than normal so as to create firm, dense fabric. Recommended yarn was used by Esther in her prototype.
