I would have loved to have been in the test kitchen when the people from Zooh Corner were developing their CritterCookies several years ago. A bit of hay, a dash of grains. Yummy. Rabbits, chinchillas and guinea pigs enjoy them, but a timothy hay-based treat just doesn't appeal to human taste buds. Granted, they do contain some fruits, veggies and grains, but still I haven't been tempted to try one. But what do I know, rabbits have a lot more taste buds than humans and they love these treats. They love all treats so don't overdo it when they beg. Find CritterCookies at the link above. They come in cute cookie shapes.
