Did you know that globally, mosquitos are the number one culprits spreading disease? In the United States, they cause a slew of problems by transmitting heartworm disease to dogs, cats, ferrets — even coyotes.
The American Heartworm Association recommends that pets, especially dogs, get tested annually for heartworm disease and receive preventive year-round. Testing is more complicated for cats.
If you’re thinking of replacing heartworm prophylaxis with topical mosquito repellants, think again. While pet-safe topicals may help keep mosquitos at bay, they do not take the place of preventives that kill heartworm larvae in animals.
Also, remember that just because a topical repellent or insecticide is approved for use in dogs does not mean it’s safe for cats. Be sure to read labels on over-the-counter products very carefully.
