Fleas

Fleas are parasites that feed on the blood of any warm-blooded body. They can live for about 100 days during which time the females produce 400-500 offspring which is 5000 or more eggs over their lifespan, allowing for phenomenal growth rates. Once the flea reaches adulthood, its primary goal is to find blood and then to reproduce. Fleas transport themselves on rodents and other mammals, and usually remain on their hosts at all times.  Ideal conditions for a flea include proper temperature, food supply and humidity. The most common species is the cat flea, which often feasts on cats, dogs and humans.
