Rabbit Parasite Prevention: Fleas, Mites, and E. Cuniculi

What Parasites Affect Rabbits?

Rabbits are susceptible to several external and internal parasites. External parasites include fleas (especially from contact with cats or dogs), Cheyletiella fur mites (causing "walking dandruff" — white flakes that move), ear mites (Psoroptes cuniculi — causing thick, dark ear crust), and fur mites (Listrophorus gibbus — usually clinically silent). Internal parasites include Encephalitozoon cuniculi (E. cuniculi — a microsporidian that causes neurological disease, kidney disease, and cataracts), pinworms (usually clinically insignificant in adult rabbits), and Eimeria (coccidia, causing diarrhea primarily in young rabbits).

First 3 Steps for Parasite Prevention

Use a rabbit-safe flea product if in contact with cats/dogs: Many flea products safe for dogs and cats are toxic for rabbits. Only use products specifically labeled for rabbits or approved by your vet. Imidacloprid (Advantage) at the correct rabbit dose is generally considered safe — never use permethrin-based products.
Check ears monthly for mite signs: Look into each ear for thick, crumbly brown crust (distinct from small amounts of normal wax). Psoroptes mites cause significant pain and head shaking. Treatment requires vet-prescribed acaricide.
Test for E. cuniculi at adoption: A blood titre for E. cuniculi antibodies is available and can indicate previous exposure. Discuss fenbendazole prophylaxis with your vet, particularly for rabbits that will be bonded with other rabbits.

When to Go to the Vet Immediately

Head tilt, loss of balance, or eye problems — E. cuniculi neurological involvement
Severe ear irritation and head shaking — Psoroptes ear mites in full-blown infestation
Any rabbit with moving skin flakes — Cheyletiella is transmissible to humans

Follow-Up Care Checklist

Annual parasite checks for outdoor rabbits and those in contact with other animals
Treat the environment for fleas if cats or dogs in the household have fleas — rabbits will be affected too
Clean and disinfect the enclosure when treating any parasite infestation to prevent reinfestation from eggs

Summary for Your Clinic Visit

Tell your vet whether the rabbit is indoor or outdoor, whether it's in contact with other animals, current parasite prevention used, and any signs of skin, ear, or neurological problems.
