From Scent Glands at www.japanese-home-gardens.com

A baby skunk makes a playful, affectionate, and responsive pet. It remains so even as an adult. Its scent glands may be left intact, as it does not use this defense upon those it knows. However if a kitten is to become a house pet, no doubt it will be given some freedom in the yard. This may expose it to stray dogs or some other frightening factor; hence it is advisable to have the scent glands removed.

During the breeding season male and female salamanders are attracted to each other by their sense of smell. It is apparent that the skin of the females possesses definite odors which attract the males, while the males have scent glands located at the base of the tail and on the under side of the head to attract the females.

In others the two cornua unite to form a single uterus or womb. The placenta is of the deciduate type and of discoid form. Rodents are extremely prolific. Most species of rodents have characteristic and penetrating odors which arise from scent glands variously located in the vicinity of the anus. The skin, generally covered with hair, is spiny in the porcupines, some genera of which possess prehensile tails. Many rodents furnish furs of value in commerce.
