How to help an overweight rabbit lose weight
Understand the risks your rabbit can face if it is overweight.
Fat rabbits are often lethargic, and are susceptible to heart, liver, and kidney disease. They may suffer from chronic diarrhea, heat stress in hot weather, splayed legs, and arthritis in later years.
Obesity can also cause breeding and birthing difficulties. Make sure your rabbit's weight is really indicative of a problem.
