Fleas are an external parasite of both dogs and cats. The adults consume up to 15 times their body weight in blood per day, making them ravenous. Pets initially become infested when adult fleas occur indoors or outdoors jump on the animal with ease- they can hop about 6 inches high!
Flea’s hitch a ride onto passing animals from kennels, groomers, etc., but pets also acquire these pesky insects through stray animals like opossums and raccoons that come wandering into yards near homes.
