What to know about heartworm disease.
Heartworm disease is a serious disease that affects cats. It is caused by foot-long worms that settle into the heart, blood vessels, and lungs of an affected pet. These types of worms can cause heart failure and lung disease and can be potentially deadly if not caught in time. Pets that survive heartworm disease often have a lower quality of life because of the damage to their organs. As April is Heartworm Awareness Month, it is important to educate yourself on what heartworm disease is and why heartworm prevention is vital to your pet’s wellbeing.
What is heartworm?
Heartworm is a type of roundworm known as dirofilariasis (or heartworm disease). The parasite that causes the disease is known as Dirofilaria immitis. It takes 6 – 7 months for larvae to mature to adulthood where it begins the reproduction cycle. A single adult heartworm can reach up to 12 inches in length and live up to seven years.
How do pets get heartworms?
Mosquitoes are the most common carrier of heartworm. A female mosquito picks up larvae in the bloodstream of an infected animal, then transmits the larvae into the next animal it bites.
Heartworm larvae take about 6 months to develop into adult worms that settle into the organs of the animal. Once the worms take hold, the adults can live and produce larvae for 2-3 years in cats.
Signs of heartworm in cats
Cats are much less likely to be afflicted by heartworms than dogs, but it’s still a possibility. When a cat gets infected by heartworm, its organs are damaged just like in dogs. The condition, heartworm associated respiratory disease (HARD) can cause symptoms that include:
- Asthma-like attacks
- Loss of appetite
- Vomiting
- Seizures
- Difficulty walking
- Fluid accumulation
Heartworm prevention is important for cats because treatment options are limited and come with a high rate of complications. Cats can live with heartworms, but they can also collapse or die when signs are first noticed.
How is heartworm tested?
Cats require a blood draw to look for antigens and antibodies in response to heartworm infection. Because cats have no approved treatment for infection, they should be put on a preventative dose as soon as possible.
