Rabbit Flea Infestation: Vet Guide for 2025 🐇🪳
By Dr Duncan Houston BVSc
📚 What Is Flea Infestation?
Flea infestation in rabbits happens when common fleas (often Cat flea, Ctenocephalides felis) live and reproduce on a rabbit’s fur; the extent depends on season, other pets or outdoor exposure :contentReference[oaicite:3]{index=3}.
⚠️ Why It Matters
- Anemia: Blood loss from many bites can lead to weakness, pale gums, even shock—especially in young bunnies :contentReference[oaicite:4]{index=4}.
- Pruritus & Skin Damage: Excessive scratching, biting, and flea allergy can cause sores, hair loss, and secondary bacterial infections :contentReference[oaicite:5]{index=5}.
- Disease Risk: Fleas may carry vector-borne illnesses; exposure indoors can reinfest rapidly.
👀 Signs & Clinical Clues
- Frequent scratching, chewing at fur, restlessness.
- Visible fleas or “flea dirt” (tiny black specks = digested blood); water test shows red ring :contentReference[oaicite:6]{index=6}.
- Patches of hair loss, scaling, scabs.
- Anemia signs: pale mucous membranes, fast heart rate, lethargy.
- Skin infections: crusts, odor, thicker fur clumps.
🔍 How It's Diagnosed
- Flea combing: Use a fine-toothed flea comb—look for live fleas or flea dirt :contentReference[oaicite:7]{index=7}.
- Skin scrapings: To differentiate mites or bacterial dermatitis.
- Bloodwork: CBC to check for anemia or secondary infection :contentReference[oaicite:8]{index=8}.
- Environmental history: Outdoors access, infested cohabitants (dogs/cats), or previous household infestations.
