fleas

Fleas are small, wingless insects that feed on the blood of mammals and birds. They are a common problem for pet owners, as they can cause itching, irritation, and even anemia in severe cases. While there are many different species of fleas, the two most common types that infest cats and dogs are Ctenocephalides felis (the cat flea) and Ctenocephalides canis (the dog flea).
