Heartworm Disease

How Heartworm Disease is Spread

The average heartworm life cycle typically follows this path:

  • A female mosquito bites an animal infected with heartworm.
  • While the mosquito feeds on the animal, they ingest the microfilariae (tiny, thread-like larvae).
  • Within 2 weeks, the microfilariae mature into infective larvae in the mosquito.
  • The female mosquito than bites a non-infected animal, transferring the larvae to their new host.
  • Once heartworm larvae are transmitted to your pet, they travel to the heart and lungs, which may take several months.
  • Adult heartworms can live for several years inside your pet, propagating and doing damage to the surrounding organs.

Why is Heartworm Deadly?

As their numbers grow, heartworms block the major arteries leading to the heart and lungs, inhibiting blood flow and forcing the organs to work much harder. Treating heartworm disease even in its less severe stage is expensive, takes time, and can be very stressful for your pet. Furthermore, treatment does not guarantee that your pet will recover 100 percent. They could spend the rest of their life living with problems left over from their infection.

There is currently no heartworm treatment available for cats.
