This parasite that is known as Dirofilaria immitis are from a species of worms (heartworms) that live in the blood, lungs or heart of animals. These animals may dogs, ferrets or even dogs, but these are not the only species of animals in which these worms live. Other mammals like foxes or coyotes are also carriers of this worm, or heartworm positive. Heartworm disease in cats is as common as it is in dogs. The affected animals can have severe damage to their organs such as the heart and lungs. And can cause heart failure or lung disease in these animals.

So even in the rare cases that these heartworms have been reported, they are not a serious disease but they may cause some symptoms like discomfort or pain or some other variable symptom.

The heartworm positive dog may have a host of this worm within its body whose number might be in the many hundreds. If a dog is heartworm positive; this means that the heartworm disease is widespread in the dog’s body. The parasite thrives inside the dogs bodies mature and become adults, reproduce and also produce offspring there. And if this heartworm disease is left untreated, it may cause long lasting damage to the dog’s body. This may include damage to the different organs like the arteries, heart and the lungs. So, even if the disease is treated, the quality of life and health will still be restrictive although the heartworm will be gone.

Heartworms in Cats

A question that is in the minds of the cat owners is, is heartworm in cats contagious? Another more pertinent question is heartworm disease in cats common? Well, in the cat’s body the heartworms are not able to survive like it does in dogs, so cats are not considered to be a natural host of heartworms. Hence they are similarly not as likely to get infections as well unlike dogs. The route through which heartworms can affect cats is by being bitten by infected mosquito.

 A cat that has been bitten by infected mosquito, will have the larvae of the heartworms in the blood. These heartworm larvae then enter blood vessels and other organs e.g. lungs. This process of this disease is several months long, and can cause these worms to wreak havoc in the body of the cat and can also grow to be foot-long worms.
