When rabbits chew their fur, it is called barbering. Barbering may be caused by several factors.
First, females that are pregnant pull the fur from their stomachs and dewlaps (the fleshy area in front of the chest) to prepare a nest for birth. However, even if a female is not pregnant, she may still exhibit this behavior. (If you think your rabbit is pregnant, provide it with proper nesting materials and a nest box, and consult your veterinarian.)
Second, when there is more than one rabbit, they may pull at each others' fur because of dominance or boredom. Introducing rabbits to toys or providing them with more exercise may prevent the behavior. But separating the rabbits may be necessary.
Third, rabbits may chew their fur because they are not getting enough dietary fiber. Something as simple as providing more access to grass hay may prevent the behavior from occurring and will ensure that the hair passes through the digestive system without causing a blockage.
Finally, barbering may be caused by an infestation of parasites, such as fleas and mites, and by skin diseases. Skin irritations are uncomfortable and can cause a rabbit to chew or pull at its fur.
