CatLax is a combination of natural ingredients which gently lubricate the digestive tract to prevent and remove any build up of hairballs. Hairballs can occur from frequent grooming hair is ingested by the cat and overtime can lodge in the digestive tract forming a cluster or hairball. Symptoms of hairballs are gagging, coughing, vomiting and constipation. CatLax is a lubricant which coats the swallowed hair allowing the hairball to transit along the digestive tract. CatLax has a mild laxative effect pushing through the hardened faecal waste until it has passed through the animal.
