Fig. 71.â Genus Notoedres. Notoedres cati, var. cati (Sarcoptes minor var. cali, Fig. 71), the chvarf sarcopt, is a small species having the body nearly spherical.

The arrangement of the stalked suckers is the same as in Sarcoptes scabiei. Course and Diagnosis.âNotoedric mange of the cat usually begins about the ears and upper part of the neck, extending over the forehead and then over the head generally. As a rule it remains limited to these regions, rarely passing to the body. The disease fol- lows the usual course and alterations of sar- coptic mange, the cat giving evidence of the mtense itchmg by frecjuentl}^ shaking the head and wipmg it with its paws. In neglected cases animals may become much emaciated and may die in a few months. Due to the wrinkled, papular, and crust}^ skin and its j^ersistencj' of location upon the head, the diagnosis of this mange on the cat is not difficult. Its differentiation from other itching skin diseases may be made certain by the discovery of the para- site, which is readily obtamed in material scraped from beneath the crusts. Auricular Mange of the Cat.â Auricular mange seldom occurs in the cat. It is caused b}' the same species of mite causing auricular mange of the dog and is similar in its symptoms and course. Scabies of the Rabbit Two species of scab mites afflict the rabbit, âNotoedres cati var. cutii- fiq. 72.âPsoroptes communis var. â cult and Psoroptes communis var. cunicuU (from photomicrograph of funiculi (Fig. 72), the latter cans- ^lounted specimen, hyHoedt). ing auricular scabies or psoroptic otacariasis. In the rabbit notoedric mange most often has its beginning about the nose, from which it extends
