Hairballs form when your cat ingests more hair than her digestive system can manage. The excess hair forms a clod with mucus and saliva, which is promptly thrown up. Your cat ingests hair through grooming of herself and other cats. To help prevent hairballs, brush your cat frequently to remove excess hair. Prevent your cat from over-grooming by reducing stress and keeping your cat busy with toys and exercise. Consider feeding your cat a hairball formula food. These foods have high fiber to assist your cat’s digestive system with passing hairballs. You cat can lick hairball gels off your finger or her paw. These gels work as a laxative to get rid of hairballs pretty quickly. A combination of these methods works best for most households. If your cat throws up large hairballs frequently, make an appointment with your Castle Hills, TX veterinarian for evaluation to rule out medical issues and prevent treatment as needed.
