Abstract:		"Male Long-Evans hooded rats were tested in a habituation-dishabituation procedure for their ability to discriminate between the urine odors of male C57BL/6J mice maintained on two different diets. There were discriminable differences between the urinary odors of two individual mice maintained on different diets. The rats did not dishabituate when presented with urine odors from two individuals on the same diet or two odor samples from the same individual. These results indicate that individual urinary odors of genetically identical mice are influenced by diet. We discuss the hypothesis that diet may act together with genetic differences, commensal bacteria, and hormonal changes to convey olfactory information used for individual recognition"
