Heartworm disease is a serious threat to cats, which can cause lung disease, heart failure, and damage to other organs in the body. Heartworm disease is transmitted to your cat by infected mosquitoes, who got infected by feeding on an infected animal. Signs of heartworm disease are lack of appetite, weight loss, periodic vomiting, coughing, and asthma-like attacks. Centragard is prescribed as a preventive treatment against heartworm disease and for the treatment and control of three of the most common intestinal parasites found in cats: hookworms, roundworms, and tapeworms. Centragard is an innovative and easy-to-use dewormer for cats, that is applied to your cat’s skin and provides one month of protection.
