Mange is a highly contagious parasitic skin disease caused by microscopic mites that infest the skin, fur, or ear canals of rabbits. Several different species of mites can cause mange in rabbits, each producing characteristic patterns of skin damage, hair loss, and intense discomfort. The most common types affecting rabbits include Sarcoptes scabiei (sarcoptic mange or scabies), Psoroptes cuniculi (ear mange), Cheyletiella parasitovorax (fur mites or walking dandruff), and occasionally Demodex cuniculi (demodectic mange). These parasites cause significant distress through intense itching, skin inflammation, and secondary complications that can severely impact a rabbit's quality of life and overall health if left untreated.
Mange mites spread readily between rabbits through direct contact and contaminated environments. The parasites complete their life cycles on or within the host's skin, with eggs, larvae, nymphs, and adults all present during active infestation. Different mite species have different behaviors: sarcoptic mites burrow into the skin to lay eggs, causing intense inflammatory reactions; psoroptic mites live on the skin surface within ear canals, creating thick crusts; and cheyletiella mites live in the fur, producing characteristic dandruff-like flaking. Understanding which type of mite is involved helps guide appropriate treatment, though many antiparasitic medications are effective against multiple mite species.
The impact of mange on rabbit health extends beyond the obvious skin damage. Intense itching causes constant scratching, head shaking, and self-trauma that can lead to open wounds and secondary bacterial infections. The stress and discomfort of severe mange commonly triggers GI stasis, a life-threatening condition in rabbits. Ear mange can progress to cause middle and inner ear infection, potentially resulting in permanent vestibular damage and head tilt. Chronic untreated mange leads to weight loss, debilitation, and overall decline in health. Young rabbits, elderly rabbits, and those with compromised immune systems are particularly vulnerable to severe disease.
With appropriate diagnosis and treatment, mange is highly curable in most cases. Antiparasitic medications including ivermectin, selamectin, and moxidectin are effective against the mites causing mange in rabbits. Treatment typically requires multiple doses to eliminate all life stages of the parasites, and environmental decontamination prevents reinfestation. Early intervention produces the best outcomes, while advanced cases may require extended treatment and management of secondary complications. A rabbit-savvy veterinarian should diagnose the specific type of mange involved and prescribe appropriate treatment, as some antiparasitic products safe for other animals are toxic to rabbits.
