If you have a rabbit that sheds their hair, this is a pretty important task.
Most rabbits will tend to shed their hair about three times a year.
Some rabbits may seem to do this continuously.
Some rabbits have pattens of shedding
When they start to shed, large amounts of hair will start to come out.
When this happens, the rabbit is naturally going to start grooming themselves.
When they do this, they will naturally injest hair.
There will always be hair lining their stomach unfortunatley.
This is unavoidable.
But you can make life a bit easier for them by grooming them.
