“Many types of social encounters also involve olfaction, from the mutual sniffing of oral glands during greeting behavior by both sexes to the monitoring of female reproduction by males….We have seen males join a mating bout after being attracted from 929.6 yards… downwind.” — Steele and Koprowski, North American Tree Squirrels

As an allergic, often congested squirrel, I’d be severely handicapped.
