Heartworm disease in cats is a serious and potentially fatal condition caused by Dirofilaria immitis . This is the same parasite that causes heartworm disease in dogs but new research shows a potential for more severe reactions and even sudden death in cats.
Cats get heartworm disease the same way dogs get it.
Mosquitoes transmit the disease by biting an infected animal, then passing the infection on to other animals they bite. Wherever dogs are at risk. Even cats that live indoors. Ask your veterinarian about your cat's risk for heartworm disease. Currently there is no approved product for treatment of heartworm disease in cats.
