No. "The main flea species that attack humans include the cat flea (Ctenocephalides felis), the dog flea (C. canis), and the human flea (Pulex irritans). The latter two species are relatively rare. The common cat flea is found on both cats and dogs, and is the species usually identified in attacks on humans and usually Cat flea is responsible for flea plagues." http://medent.usyd.edu.au/fact/fleas.htm "The human flea, Pulex irritans, is a cosmopolitan flea species that has, in spite of the common name, a wide host spectrum ... including dogs and wild canids, monkeys in captivity, opossums, domestic cats, wild felids in captivity, chickens, black and Norwegian rats, wild rodents, pigs, free-tail bats, and other species." http://en.wikipedia.org/wiki/Human_flea Mar 20 10, 6:38 AM
