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:
“The animals that depend on instinct have an inherent knowledge of the laws of economics and of how to apply them; Man, with his powers of reason, has reduced economics to the level of a farce which is at once funnier and more tragic than Tobacco Road.”
—James Thurber (1894–1961)
“The alcoholic trance is not just a haze, as though the eyes were also unshaven. It is not a mere buzzing in the ears, a dizziness or disturbance of balance. One arrives in the garden again, at nursery time, when the gentle animals are fed and in all the world there are only toys.”
—William Gass (b. 1924)
