What should be used to treat a cat's lesions caused by fleas? - briefly
Use a veterinarian‑approved flea control product (spot‑on, oral, or collar) to eradicate the parasites, and treat the irritated skin with a prescribed anti‑inflammatory or antibiotic ointment. Follow the vet’s dosage and application instructions for both therapies.
What should be used to treat a cat's lesions caused by fleas? - in detail
Flea‑induced skin lesions in cats require a three‑pronged approach: immediate relief, eradication of the parasite, and prevention of recurrence.
First, soothe inflamed skin and prevent secondary infection. Apply a veterinarian‑approved topical antiseptic or a mild corticosteroid spray to reduce itching and swelling. For open wounds, clean the area with sterile saline, then cover with a non‑adhesive gauze pad impregnated with a broad‑spectrum antibacterial ointment (e.g., mupirocin or fusidic acid). Systemic analgesics such as buprenorphine may be prescribed for severe discomfort.
Second, eliminate the flea burden. Administer an oral adulticide (e.g., nitenpyrrolidine or spinosad) according to the cat’s weight and health status. Complement oral treatment with a monthly topical product containing fipronil, imidacloprid, or selamectin to target emerging fleas and prevent re‑infestation. Treat all cohabiting animals simultaneously to break the life cycle.
Third, interrupt the environmental cycle. Vacuum carpets, upholstery, and bedding thoroughly; discard vacuum bags or empty canisters immediately. Wash the cat’s bedding and any washable fabrics in hot water (≥ 60 °C). Apply an environmental spray containing an insect growth regulator (e.g., methoprene or pyriproxyfen) to indoor areas where fleas may develop.
Additional considerations:
- Conduct a complete physical examination to rule out allergic dermatitis, mange, or other dermatological conditions that may mimic flea allergy.
- Perform a fecal examination if systemic illness is suspected, as stress from flea bites can exacerbate underlying diseases.
- Monitor the cat’s weight and overall health; severe infestations can lead to anemia, especially in kittens or debilitated adults.
- Schedule a follow‑up visit within 7–10 days to assess wound healing and adjust therapy if necessary.
By combining symptomatic care, effective parasitic control, and rigorous environmental management, the lesions will resolve, and the risk of future flea‑related skin problems will be minimized.
