Author Lucille Moore has given us a wonderful new book entitled Rabbit Nutrition and Nutritional Healing (USD $15.95 from Amazon). What to feed the little stinkers is actually a complicated subject, raising more questions than one might suppose. This book has a comfortable margin of useful answers, and clarifying advice, all written in non-technical language. An excellent one volume survey of an important aspect of rabbit care (the rabbits think it is the most important aspect).
By the way -- the bunny nose, above, is from Julie Behm of Quirky Bunny.
