Cat flea (Ctenocephalides felis). Similar to a dog flea, it usually lives on cats and dogs. The most convinient developing conditions for this kind of parasite are in humid and moderate temperatures. It often sucks blood. Females lay eggs on the host’s fur where they develop. The bites of this parasite are painful. The bite spots are blushing swellings and red. The skin lesions are difficult to cure. Animals with cat flea presence might suffer from anaemia and weight loss. Because the infected animals live close to people they may spread infection and diseases.
