In Animals
Individual animals regularly clean themselves and put their fur, feathers or other skin coverings in good order. This activity is known as personal grooming, a form of hygiene. Extracting foreign objects such as insects, leaves, dirt, twigs and parasites, are all forms of grooming. Among animals, birds spend considerable time preening their feathers. This is done to remove ectoparasites, keep them in good aerodynamic condition, and waterproof them. To do that, they use the preen oil secreted by the uropygial gland, the dust of down feathers, or other means such as dust-bathing or anting. During oil spills, animal conservationists that rescue penguins sometimes dress them in knitted sweaters to stop them from preening and thereby ingesting the mineral oil which is poisonous. Felidae cats are well known for their extensive grooming. One reason advanced for such grooming is to remove all traces of blood and other matter so as to not alert prey with the scent. Cats groom so much that they often produce hairballs from the fur they ingest.

Famous quotes containing the word animals:
“Humans are amphibians—half spirit and half animal.... As spirits they belong to the eternal world, but as animals they inhabit time.”
—C.S. (Clive Staples)
“The moles nested in my cellar, nibbling every third potato, and making a snug bed even there of some hair left after plastering and of brown paper; for even the wildest animals love comfort and warmth as well as man, and they survive the winter only because they are so careful to secure them.”
—Henry David Thoreau (1817–1862)
