Fleas are a small parasitic insect that feeds on the blood of domesticated pets, wild animals, and humans. They are tiny in stature, making them hard to detect without intense examination. The cat flea is the most common of them all; however, many species of fleas exist. They are also very tough to exterminate.
Fleas will lie in wait for an animal to pass by and then jump onto the new host. They have heightened senses that provide them with the ability to detect increases in temperature and carbon dioxide. They also use changes in light and shadow to locate their next host. These abilities enable them to find their next meal with ease.
