How Much Do You Know About Flea and Heartworm? Take the quiz!

Posted on 25 Feb 2026 | Posted in Petcyclopedia

True or False: Fleas are annoying, but they aren't actually harmful to pets.

Answer: False.

Although fleas are small, they can cause a number of health problems for cats and dogs. Flea allergy dermatitis, itchiness, and other skin complaints are common side-effects of an untreated flea infestation. Fleas can also pass internal parasites to pets, and long-term infestations may cause anemia in young animals.

Using Revolution every month helps stop fleas from infesting your pet and prevents these flea-related problems from occurring.

How do heartworms infect pets?

Heartworm is an internal parasite which infects cats and dogs through an intermediate host — the mosquito. When a mosquito infected with heartworm larvae bites an animal, the larvae are passed into the animal's bloodstream.

The larvae then migrate to the heart and lungs, where they develop into mature heartworms. Heartworm infestation is a very serious condition. Preventative treatment with Revolution is always preferable and far less stressful than having to treat a pet with curative medication.

True or False: Revolution must be reapplied if your pet goes swimming or gets wet in the rain.

Answer: False.

The anti-parasitic medicines Revolution for Cats and Revolution for Dogs contain ingredients that are water-fast once dry. Two hours after application, the product remains effective against parasites even if your pet swims, is bathed, or gets wet.

Revolution provides broad-spectrum protection against fleas, heartworm, and other parasites for a full month — no matter what your pet gets up to!

What should you do if you see fleas or evidence of fleas on your pet?

If you notice fleas or signs of fleas — such as excessive scratching or black specks in your pet’s fur — the first action you should take is to apply Revolution.

Revolution kills adult fleas and prevents flea eggs from hatching, effectively breaking the flea life cycle and bringing the infestation to a rapid end.

True or False: Revolution can be applied to pets from the age of six weeks.

Answer: True.

Pets of all ages need help from their owners to stay free from infestation by fleas and heartworm. Revolution offers a practical and safe way to protect even puppies and kittens from these parasites.

Revolution for Cats and Revolution for Dogs are approved for use on pets aged six weeks and over.
