Abstract Wild Norway rats ( Rattus norvegicus ) with scar-markings, presumably an index of low social status, were exclusive in drinking excessive amounts of water (> 1cc/g body weight/day) after capture. Unscarred wild rats had intakes similar to albino rats after 50 days captivity. In a second experiment there was no reliable relation between adrenal weight of captives and scar-marking or time in captivity up to 1 yr.
