As described in Section 4 and summarized in Table 2, all of the high alcohol-consuming rat lines, excepting the UChB line in some cases, described herein meet the basic criteria of voluntary ethanol intake (see Section 5 for a discussion of procedures modeling this behavior) and the subsequent development of tolerance and/or dependence, as well as displaying relapse-like behavior and the ability to work/operantly respond for ethanol (see Section 5 for a discussion of procedures modeling these latter two behaviors). When examining other putative animal models of alcoholism, these rudimentary criteria and whether high alcohol consumption will be maintained in the presence of another palatable fluid have been evaluated. Thus, the Fawn-Hooded (FH/WJD: Overstreet et al., 2007) inbred and the Warsaw High-Preferring (WHP: Dyr and Kostowski, 2008) selectively bred rat lines meet these basic criteria but fail to meet the criterion of preferring a sweet solution over ethanol. While there is evidence that the alcohol-preferring P rat line meets the criterion of a preference for ethanol in the presence of another palatable solution (see McMillen and Williams, 1995 for discussion
