Seeing a rabbit pull out its fur can be alarming for any pet owner. This behavior may be a sign of an underlying problem affecting your pet. However, it is also possible that a rabbit with patches of fur missing in specific areas is simply engaging in a natural behavior. Let's look at the reasons for this unusual behavior.

1. Stress and anxiety

Rabbits are sensitive animals and can be greatly affected by their surroundings. When subjected to stressors like loud noises, confined spaces, lack of mental stimulation, or social isolation, they may exhibit abnormal behaviors, including fur pulling. 

2. Medical problems

Hair pulling in rabbits can also be due to medical issues such as allergies, skin conditions, parasites or even digestive problems. If you suspect a medical problem, it is recommended that you contact your veterinarian for diagnosis and treatment.

3. Shedding

Rabbits periodically go through a molting process where old fur is replaced by new fur. During this process, they may lick, scratch, or pull out fur.

Rabbits groom themselves by eating their own fur to aid digestion, and may also pluck out loose or dead hair with their teeth and paws during shedding.

4. Birthing

In rabbits, hair pulling is often associated with the birthing process. This behavior is usually observed in pregnant rabbits immediately before giving birth. In preparation for the arrival of their babies, pregnant females may pluck fur, especially from the belly and chest areas.

5. Instincts

Hair pulling in rabbits may be due to their natural instincts. In the wild, rabbits pluck fur to use as material to build dens or nests.

6. Pica syndrome

Rabbits are intelligent and social creatures that require a lot of mental and physical stimulation to stay happy and healthy. Pica syndrome is a condition in which an animal eats non-food items. This is a relatively common condition in rabbits and can be caused by a number of factors including boredom, lack of nutrition and disease.
