Fleas are the most common external parasite found on cats. Although fleas are more likely to be a problem during warm-weather months, they can also cause problems during cooler seasons due to their ability to continue their life cycle indoors.
How will fleas affect your cat?
The first sign of fleas for many pet owners is their cat’s repeated itching, scratching and chewing. You may see fleas or flea dirt (feces) on your cat, although cats are very good at keeping their coats clean. A cat’s constant itching and scratching may lead to visible patches of hair loss and reddened, irritated skin. Fleas may also transmit other parasites, such as tapeworms, to a cat.
