Cats may lick iron filings because they have a certain need for iron. Iron is an essential trace element in humans and animals. It helps the formation and metabolism of red blood cells in the blood. Some cats are deficient in iron due to insufficient intake or other reasons. At this time, they may look for iron-containing substances to supplement. Iron filings are waste products that contain iron, and cats may smell the iron and try to lick it to satisfy their needs. During the process of licking iron filings, cats may inhale some small iron particles, which can replenish the iron needed in the body.
However, licking iron filings may also be harmful to the health of cats, because iron filings may contain other harmful substances. If your cat often licks iron filings, it is recommended to take it to the doctor promptly to ensure that it is in good health.
