Cats are susceptible to heartworms but less so than dogs. Their
immune systems mount an attack against the microfilaria but some do get through and mature in the heart of cats resulting in serious disease. It is recommended that all cats both
indoor and outdoor be kept on a heartworm preventive as a recent study showed that a high percentage of all cats had antibodies to heartworms indicating exposure. The following
