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:
“Russian forests crash down under the axe, billions of trees are dying, the habitations of animals and birds are layed waste, rivers grow shallow and dry up, marvelous landscapes are disappearing forever.... Man is endowed with creativity in order to multiply that which has been given him; he has not created, but destroyed. There are fewer and fewer forests, rivers are drying up, wildlife has become extinct, the climate is ruined, and the earth is becoming ever poorer and uglier.”
—Anton Pavlovich Chekhov (1860–1904)
“Feet are considered a delicacy among certain animals, you know.... In fact, there are certain man-eating animals who will eat only the feet, leave everything else, will not touch one other thing.”
—Blake Edwards (b. 1922)
