📌 What Are Lice in Cats?
Cats are affected by chewing lice—specifically Felicola subrostratus—tiny wingless insects (1–2 mm) that feed on skin debris, not blood :contentReference[oaicite:3]{index=3}. These parasites require direct contact or shared grooming items for transmission and cannot transfer to humans or dogs :contentReference[oaicite:4]{index=4}.
⚠️ Risk Factors & Who Gets Them
- Poor grooming—especially in older, neglected, or immunocompromised cats :contentReference[oaicite:5]{index=5}
- Multi-cat households, shelters, or outdoor cats with frequent contact :contentReference[oaicite:6]{index=6}
- Dirty environments and shared bedding/grooming supplies :contentReference[oaicite:7]{index=7}
- Chewing lice don’t survive more than 3–7 days off the cat :contentReference[oaicite:8]{index=8}
🔍 Signs & Symptoms
Look for:
- Intense itching and scratching :contentReference[oaicite:9]{index=9}
- Dry, scruffy, unkempt coat with visible nits or lice on skin :contentReference[oaicite:10]{index=10}

🧴 Vet-Recommended Treatments
Veterinary oversight is essential—do NOT use dog or human insecticides. Your vet may recommend:
- Spot-on products: Fipronil or selamectin—kill lice on contact :contentReference[oaicite:15]{index=15}
- Shampoos or dips: Special pyrethrin or lime sulfur solutions—especially in kittens or resistant cases :contentReference[oaicite:16]{index=16}
- Repeat dosing: Treat twice, 7–10 days apart, to eradicate hatching nits :contentReference[oaicite:17]{index=17}
- Shaving: Trim matted fur for better insecticide contact :contentReference[oaicite:18]{index=18}
🏡 Home & Environment Control

- Wash bedding, toys, combs, carriers in hot soapy water or treat with sprays :contentReference[oaicite:20]{index=20}
