Lemmings hurt in a fight should be placed in terraria or cages separate from the aggressor as soon as possible. Also, their natural tendency to scratch and lick at wounds can cause slow healing. A veterinarian may prescribe antibiotics and infection retardants to help an injured lemming, generally at reasonable costs. While it can be very difficult to convince an injured lemming to drink its medicated drops or eat food laced with medicine, a good trick is to place drops of medicine on the lemming's nose. Through licking itself clean, the lemming will ingest the medicine.
