Rat snake
Rat Rat (r[a^]t), n. [AS. r[ae]t; akin to D. rat, OHG. rato, ratta, G. ratte, ratze, OLG. ratta, LG. & Dan. rotte, Sw. r[*a]tta, F. rat, Ir. & Gael radan, Armor. raz, of unknown origin. Cf. {Raccoon}.] 1. (Zo["o]l.) One of several species of small rodents of the genus {Rattus} (formerly included in {Mus}) and allied genera, of the family {Muridae}, distinguished from mice primarily by being larger. They infest houses, stores, and ships, especially the Norway rat, also called {brown rat}, ({Rattus norvegicus} formerly {Mus decumanus}), the black rat ({Rattus rattus} formerly {Mus rattus}), and the roof rat (formerly {Mus Alexandrinus}, now included in {Rattus rattus}). These were introduced into America from the Old World. The white rat used most commonly in laboratories is primarily a strain derived from {Rattus rattus}. [1913 Webster +PJC]

2. A round and tapering mass of hair, or similar material, used by women to support the puffs and rolls of their natural hair. [Local, U.S.] [1913 Webster]

3. One who deserts his party or associates; hence, in the trades, one who works for lower wages than those prescribed by a trades union. [Cant] [1913 Webster]

Note: ``It so chanced that, not long after the accession of the house of Hanover, some of the brown, that is the German or Norway, rats, were first brought over to this country (in some timber as is said); and being much stronger than the black, or, till then, the common, rats, they in many places quite extirpated the latter. The word (both the noun and the verb to rat) was first, as we have seen, leveled at the converts to the government of George the First, but has by degrees obtained a wider meaning, and come to be applied to any sudden and mercenary change in politics.'' --Lord Mahon. [1913 Webster]
