The distinction between the terms renminbi and yuan is similar to that between sterling and pound, which respectively refer to the British currency and its primary unit. One yuan is subdivided into 10 jiao (Chinese: è§; pinyin: jiÇo), and a jiao in turn is subdivided into 10 fen (Chinese: å; pinyin: fÄn).
Fleas are attracted to the warmth that the bodies of their hosts emit, vibrations and carbon dioxide, and they also like warm and carpeted environments where their hosts rest. These parasites feed on the blood of their hosts and can cause a number of conditions including skin infection and irritation, loss of hair and lethargy in their hosts.
The flea's host is a warm-blooded animal such as a dog or cat (or even humans!) However, the various flea stages are quite resistant to freezing temperatures. The adult female flea typically lives for several weeks on the pet.
