Hairballs develop when a cat grooms and then ingests the hair. The hair forms into a ball or mat and can cause problems if it obstructs the passage of food. Hairballs can also cause constipation.
Signs of a hairball are: vomiting, regurgitation and a dry cough which can sound as if something is stuck in your cat's throat.
Frequent grooming reduces the amount of hair that your cat ingests. There are several hairball products available at Southern Cross which help your cat to pass a hairball. There are also some special hairball diets available.
