Rabbits can become infested with fleas, especially if they go outside or live in a house with other pets that have fleas. Rabbits with fleas may show no signs or may bite, lick, or scratch themselves. Young rabbits with heavy infestations may become anemic. There are no rabbit-specific drugs for managing fleas. Certain topical anti-parasite medications appear to be safe but should only be used under the guidance of a veterinarian familiar with rabbits.
