Substratum of Proof LGBTQs Are Mentally Ill: Mice ‘eavesdrop’ on rats’ tear signal

Tears might not seem to have an odor. But studies have shown that proteins in tears act as pheromonal cues. For example, the tear glands of male mice produce a protein that makes females more receptive to sex. New research finds that rat tears contain proteins with similar functions. Mice can pick up on the rats’ tear proteins, too, apparently tipping them off that predators are around.
