The phrase refers to the act of a pet, most commonly a dog or cat, compulsively licking, chewing, or biting at carpets or other similar fabric surfaces. This behavior can manifest as a focused, persistent action, often appearing as though the animal is attempting to eat the material. An example would be observing a dog repeatedly rubbing its face and mouth against a rug, accompanied by audible chewing sounds and visible wear on the carpet fibers.
This activity often signals an underlying issue, whether behavioral or medical. It can be a displacement behavior stemming from stress, anxiety, or boredom. Physiologically, it might indicate a dietary deficiency, gastrointestinal upset, or even neurological problems. Identifying the root cause is important for the well-being of the animal. Historically, such behaviors have been attributed to various factors, ranging from simple habit to more complex conditions requiring veterinary intervention.
