FAQ

What is heartworm disease?

Heartworm disease in cats (dirofilariasis) is a serious and potentially fatal disease. Heartworms spend their adult lives in the pulmonary arteries. The adult worms can cause lasting damage to the heart, lungs and arteries.

How do cats get heartworms?

Heartworms are transmitted from one cat to another by mosquitoes, which pick up tiny immature heartworms, called microfilariae, when they bite an infected cat. Larvae develop and are then transmitted to another cat when that cat is bitten by the infected mosquito.

Where are cats at risk for heartworm infection?

All cats are at risk for heartworm disease, no matter where they live—heartworms don't discriminate based on geography. In the past, heartworm disease in the United States was primarily limited to the South and Southeast regions. However, it is now found in all 50 states, in Canada, and is spreading to new areas each year. The American Heartworm Society notes that uncared-for cats and certain wildlife can be carriers of heartworms. Mosquitoes blown great distances by the wind and the transportation of infected pets to different geographic locations can all contribute to the spread of heartworm disease.

What are the signs of heartworm infection?

Signs of heartworm disease can be subtle and difficult to detect until its later stages. As the disease progresses, signs begin to appear. Contact your veterinarian immediately if you notice coughing, difficulty breathing, sluggishness and less energy for exercise in your cat. Adult heartworms cause serious harm to your cat's heart, lungs and certain internal organs. Left untreated, heartworm disease can result in loss of consciousness and death.

How are cats tested for heartworm infection?

The most common method for heartworm testing is for a veterinarian to collect a small blood sample from a cat and evaluate the sample using a specialized test kit to detect the presence of adult heartworms.

How can heartworm disease in cats be prevented?

Pet owners can use Heartgard (ivermectin) to help prevent heartworm disease. Heartgard kills tissue larval stages of heartworms and helps prevent them from developing into adults and causing heartworm disease. In an unprotected cat, heartworm larvae mature into adults and ultimately migrate to the arteries of the lungs.

How long do I have to give my cat Heartgard?

Monthly use of Heartgard is essential because it cannot be determined with certainty when the threat of mosquitoes has passed. Talk to your veterinarian for dose and regimen recommendations.

Can heartworm disease be treated?

Although it is possible to treat heartworm disease if a cat becomes infected, it is difficult, expensive and risky, particularly in cats that have begun to exhibit clinical signs of infection.

What if my cat becomes infected with heartworms?

There are treatment options available to kill adult heartworms in cats that have become infected. Treating cats with heartworm disease starts with a thorough physical examination by the veterinarian. The veterinarian will then discuss treatment options with you. Typically, the cat is hospitalized during the treatment period. Because there is a risk of blood clots or worm debris blocking blood vessels from adult heartworm treatment, the cat must then remain quiet in close confinement for another 4 to 6 weeks after treatment. A second round of treatment may be required for some cats. The veterinarian may also give your cat a treatment to rid it of the immature larvae that are circulating through the blood stream.

Is Heartgard safe to use in any breed of cat?

Heartgard is safe and effective in any breed of cat when used as directed.

Can my cat "get" heartworm disease directly from an infected cat?

No, the way cats become infected is via a bite from a mosquito that is carrying heartworm larvae.

Are nursing kittens immune to heartworm disease if the mother is receiving Heartgard?

No. kittens that are nursing may become infected. Heartgard can be used in kittens as young as 6 weeks of age—and kittens benefit from the ability of Heartgard to treat and control roundworms and hookworms.

  • My picky cat actually eats these.

    Let me preface this by saying that Mr. Darcy will not touch ANY cat treats and is really picky about foods in general. Believe me, I've tried them all. Different ingredients, different flavors, even cat-friendly people foods. I have no idea why, but he absolutely LOVES these Heartgard Chewables and takes his chew every month with zero problems (sigh of relief here). I highly recommend these as an easy and hassle-free way to protect your best friend. Just ONE heart worm can kill a cat so preventative measures are really the only way to protect them.

    Vet said heartworm is the main concern for cats as it can kill them. I bought this but do have to force feed her. It’s fine though and most affordable option.

    My two cats love the Heartgard! They are heartworm negative when they have complete labs done with annual physical and vaccinations. I pop the treat out of the packet and they know the sound....come running! Then look at me like "Just one treat?"
