What is the recommended treatment for pinworms in rabbits?

The recommended treatment for pinworms in rabbits is fenbendazole. This medication is a broad-spectrum anthelmintic, which means it is effective against a variety of intestinal parasites, including pinworms. Fenbendazole works by disrupting the energy metabolism of the parasites, ultimately leading to their death and elimination from the rabbit's system. This treatment is commonly utilized in veterinary medicine and is considered safe and effective for rabbits, making it the appropriate choice for managing pinworm infestations.

The other treatments listed do not target pinworms specifically, nor are they effective for this type of parasitic infection. Topical antifungal cream is designed to address fungal infections, and heavy oil application is typically used for other parasite issues, such as mites or fleas. Intravenous antibiotics are used to treat bacterial infections, not parasitic infestations, and could potentially harm the rabbit if misused in this context. Therefore, the choice of fenbendazole is both targeted and effective for pinworm treatment in rabbits.
