How to treat scabies mite on a cat? - briefly
Administer a veterinarian‑prescribed scabicide such as selamectin, moxidectin, or a lime‑sulfur dip, and simultaneously clean the environment by vacuuming carpets, washing bedding, and disinfecting surfaces. Re‑examine the cat after two weeks to confirm eradication and repeat treatment if any signs persist.
How to treat scabies mite on a cat? - in detail
Scabies in felines is caused by the mite Sarcoptes scabiei and produces intense itching, hair loss, and crusted skin lesions. Prompt intervention stops the parasite’s life cycle, prevents secondary infections, and reduces discomfort.
The first step is a veterinary examination. The clinician confirms the diagnosis by skin scraping, microscopic identification of mites, or by evaluating characteristic lesions. Once confirmed, treatment proceeds with systemic and topical measures.
Systemic medication
- Ivermectin: dosage 0.2–0.4 mg/kg orally or subcutaneously, repeated after 7–10 days to eliminate newly hatched mites.
- Selamectin: 6 mg/kg topically applied once, with a second dose 2 weeks later.
- Moxidectin: 0.2 mg/kg orally, repeat after 10 days if needed.
Topical therapy
- Lime sulfur dip: 2 % solution applied to the entire coat, left for 10 minutes, then rinsed. Repeat weekly for three applications.
- Benzoyl peroxide shampoo (5 %): used every 3 days for two weeks to reduce surface mites and soothe inflammation.
Adjunct care
- Antihistamines (e.g., diphenhydramine 2 mg/kg PO q12h) alleviate pruritus.
- Broad‑spectrum antibiotics treat bacterial pyoderma secondary to scratching.
- Environmental decontamination: wash bedding, blankets, and toys at >60 °C; vacuum carpets; apply a residual acaricide to the household environment if infestation is severe.
Monitoring
- Re‑examine the cat 2 weeks after the initial treatment to assess lesion resolution and confirm mite clearance.
- Continue observation for at least 4 weeks; any recurrence warrants a repeat dose or alternative drug.
Precautions
- Ivermectin is contraindicated in breeds with MDR1 gene mutations; confirm breed susceptibility before use.
- Pregnant or lactating queens require veterinary discretion; topical options are preferred.
Following this protocol eradicates the mite, restores skin integrity, and minimizes the risk of relapse. Regular veterinary follow‑up ensures successful outcome.
