Fleas have 11 day gestation periods. Flea eggs only need a few days after being layed to hatch.
Veterinary medicine is the branch of science that deals with the prevention, diagnosis and treatment of disease, disorder and injury in animals. The scope of veterinary medicine is wide, covering all animal species, both domesticated and wild, with a wide range of conditions which can affect different species.
Veterinary medicine is widely practiced, both with and without professional supervision. Professional care is most often led by a veterinary physician (also known as a vet, veterinary surgeon or veterinarian), but also by paraveterinary workers such as veterinary nurses or technicians. This can be augmented by other paraprofessionals with specific specialisms such as animal physiotherapy or dentistry, and species relevant roles such as farriers.
The health of domestic cats is a well studied area in veterinary medicine.
Topics include infectious and genetic diseases, diet and nutrition and non-therapeutic surgical procedures such as neutering and declawing.
Oriental rat flea
The dog flea (Ctenocephalides canis) is a species of flea that lives as an ectoparasite on a wide variety of mammals, particularly the domestic dog and cat. It closely resembles the cat flea, Ctenophalides felis, which can live on a wider range of animals and is generally more prevalent worldwide.
The dog flea is troublesome because it can spread Dipylidium caninum.
The Oriental rat flea (Xenopsylla cheopis), also known as the tropical rat flea, is a parasite of rodents, primarily of the genus Rattus, and is a primary vector for bubonic plague and murine typhus. This occurs when the flea has fed on an infected rodent, and then bites a human.
