How Large Are Cat Fleas?

The size of cat fleas depends on the host. Fleas range from a pinhead size to about an eighth of an inch. They have a flat body, short antennae, and a saw-toothed jaw and a slender sucking snout. The largest adult fleas can jump up to seven feet. Their mouths have three parts: two petal-like segments that pierce the blood vessel, and the third part of the mouth is called a pronotal comb.

Adult cat fleas can live without food for months at a time, but they require a blood meal before they lay eggs. Depending on the temperature, humidity, and food supply, a single female cat flea can lay up to 4,000 eggs during her lifetime. During the life cycle, cat fleas go through four stages. Their life cycle may last just two to three weeks, or it may last for a year.

The most common source of cat fleas is central heating and carpets. These conditions create a perfect environment for fleas to grow year-round. Fleas prefer warm, moist places. Their bites can cause severe itching and allergic reactions. Fleas are flat, dark-brown, wingless insects that are approximately one eighth inch long. Flea eggs are the size of dust particles and their larvae have dark heads and lighter bodies.

Cat fleas are not only harmful to your cat, but they can be harmful to humans. Their bites are often accompanied by a red itchy rash. They can even cause serious allergic reactions in humans. In severe cases, the infection may require intensive care.
