Abstract: Objective To understand the breeding condition of dogs and cats and their cat flea, Ctenocephalides felis, infection in several areas of China, so as to provide basic evidence for cat flea and related infectious diseases prevention and control. Methods Door-to-door household survey was used to know the dogs and cats feeding condition in the suburb of Beijing, and rural areas of Qingdao of Shandong province and Dali of Yunnan province. C. felie abundance in stray cats, domestic dogs and cats were evaluated using body surface examination, free flea collection on the ground, flea eggs investigation as well as retrospective survey methods; and the seasonal fluctuation of C. felis in suburb of Beijing was studied using the flea eggs investigated method. Results (1) In Beijing suburb, 64.52%-83.87% of peasant households kept dogs with an average of 0.84-1.87 dogs per household, 69.2%-86.8% of the dogs were not chained, and 2.94%-6.45% of peasant households had free- roaming cats. In rural areas of Pingdu Qingdao of Shandong province 40.43% of households kept dogs, with an average of 0.50dog per household and more than 36.5% of those dogs were not chained. (2) The infection rate of C. felis in cat in rural areas of Qingdao and Beijing was 100%, while only 3.85%-19.15% of dogs were infected with Pulex irritans and C. felis. (3) In winter, C. felis still could lay a large amount of eggs in Beijing. Conclusion There were a great number of domestic dogs but few domestic cats in the rural and urban-rural areas of China, most cats were homeless. C. felis can develop on the surface of cat throughout the year. It is very important to enhance the management of stray cats and to pay more attention to the prevention and control of C. felis and other infectious diseases.
