Nope, while the dog is a natural host for this parasite, cats are considered resistant hosts. This means that cats usually have fewer worms that do not multiply as rapidly or live as long (usually around 2-4 years), and a purportedly lower rate of infection from exposure. An infected dog may harbor 50 to 100 worms, but a recent study on feline heartworm disease from Auburn University found only an average of four worms per cat. However, the feline body’s response is so severe that even these few worms can cause significant damage. Heartworm prevention, testing, and infection works a little bit differently in cats than dogs but the basic principle is the same: during the younger stages in their life the worms are susceptible to a low-risk, low-cost treatment option but if they’re left untreated for too long they rapidly become resistant to these and start requiring more toxic and dangerous treatments.
