What animals somtimes needs to be oiled?

Certain animals, like birds, may require oiling when they become coated in oil due to spills or contamination, which can impair their ability to regulate body temperature and fly. Sea otters also need assistance when their fur becomes matted with oil, as their fur is essential for insulation. In these cases, wildlife rehabilitation teams may apply specialized oils or treatments to help clean and restore the animals' natural oils.
