Most pet owners assume mange is a dog problem. The reality is that cats get it too — and feline mange is frequently misdiagnosed as allergies or fungal infections for weeks before the right answer emerges. By then, the cat is often miserable, the household is stressed, and the vet bills are higher than they’d have been with an earlier diagnosis.
Cat mange refers to a skin infestation by microscopic mites. The two main types are notoedric mange (caused by Notoedres cati) and demodectic mange (caused by Demodex cati or Demodex gatoi). Treatment costs range from $150 to $800, with severe or multi-cat cases potentially running higher.
What Type of Mange Does Your Cat Have?
Type matters a lot — both for treatment and for contagion risk.
Notoedric mange (Notoedres cati) is the more common and more aggressive form. It causes intense itching, crusting, and hair loss starting around the face, ears, and neck. It spreads rapidly to other cats and can temporarily infest humans, causing a self-limiting rash. The ASPCA lists notoedric mange as a significant welfare concern in crowded or outdoor cat populations because of how quickly it spreads.
Demodectic mange in cats is caused by two distinct mite species:
- Demodex cati — follicular mite, usually associated with immune suppression (FIV, FeLV, diabetes, or steroid use)
- Demodex gatoi — superficial mite, highly contagious between cats
Knowing which type you’re dealing with shapes both the treatment plan and the cost.
- Vet exam: $75–$200
- Skin scraping (in-clinic): $40–$80
- Ear cytology (if ear involvement): $40–$70
- Prescription selamectin (Revolution): $30–$60 per dose
- Prescription doramectin or ivermectin injections: $30–$80 per injection
- Lime sulfur dips: $30–$80 per session (clinic) or $20–$50 DIY
- Oral fluralaner (Bravecto cat): $60–$90 per dose
- Recheck exams: $60–$120 each
How Vets Diagnose Mange
The gold-standard diagnosis is a skin scraping: the vet uses a blade to gently scrape the surface of an affected skin area, then examines the sample under a microscope for mites. It’s quick and inexpensive.
For Demodex gatoi specifically, superficial scrapings can miss the mite — this species is easily removed by the cat’s own grooming. Vets may use fecal flotation or tape preparations instead, since grooming cats ingest mites and they show up in stool samples.
| Diagnostic Test | Cost Range | Notes |
|---|---|---|
| Physical exam | $75–$200 | Often suggestive but not definitive |
| Skin scraping (microscopy) | $40–$80 | Best for notoedric and follicular Demodex |
| Fecal flotation | $40–$70 | Useful for D. gatoi |
| Tape cytology | $30–$50 | Adjunct for superficial mites |
| Skin biopsy | $150–$400 | Reserved for atypical or refractory cases |
Treatment Options and What They Cost
Treatment depends on the mite type and the cat’s overall health.
Selamectin (Revolution) is the most commonly prescribed first-line treatment for notoedric mange. It’s applied topically between the shoulder blades once monthly, is safe for cats, and eliminates both surface and deeper mites. Expect $30–$60 per dose, with most cats needing 2–4 doses over a 6–12 week treatment course. Total medication cost: $60–$240.
Fluralaner (Bravecto for Cats) is a newer option that’s been shown effective against both notoedric and demodectic mange. A single oral dose costs $60–$90 and provides 12 weeks of coverage. It’s become a popular choice for cats that won’t tolerate topical treatments or lime sulfur dips.
Lime sulfur dips remain an effective and affordable option, especially for notoedric mange. The sulfur compound kills mites on contact. At-clinic dips run $30–$80 each, and most treatment protocols call for weekly dips for 6 weeks. That’s a potential total of $180–$480 in dip sessions alone — though many owners learn to apply the diluted solution at home after the first session.
Ivermectin or doramectin injections are sometimes used off-label by vets for cats that don’t respond to topical treatments. These run $30–$80 per injection, typically given every 1–2 weeks. Important: ivermectin is potentially toxic in cats at high doses — this should only be done under direct veterinary supervision with careful weight-based dosing.
Never use dog mange products on cats. Many canine flea and mite treatments contain permethrin, which is highly toxic to cats. Even brief exposure can cause severe neurological reactions. Always confirm any product is specifically labeled for feline use, and call your vet or ASPCA Animal Poison Control (888-426-4435) immediately if accidental exposure occurs.
Multi-Cat Households: Plan for More
If your cat lives with other cats, assume exposure. Notoedres cati and Demodex gatoi both spread through direct contact, and cats sharing bedding, grooming each other, or eating from the same bowls are all at risk.
The AVMA notes that in multi-cat environments, treating only symptomatic animals often leads to re-infestation from untreated household members. Most vets will recommend treating all in-contact cats simultaneously, even those not yet showing signs.
For a two-cat household, budget approximately $300–$600 for full diagnosis and treatment of both animals. Three or more cats can push that to $500–$1,000 or more depending on severity.
Recheck Costs
Mange requires follow-up. A recheck scraping 3–4 weeks into treatment confirms whether mite numbers are declining. Most vets recommend a second recheck at treatment completion. At $60–$120 per visit, plan for 2 rechecks minimum, adding $120–$240 to the total.
| Scenario | Estimated Total Cost |
|---|---|
| Single cat, notoedric, mild | $150–$350 |
| Single cat, notoedric, moderate | $350–$600 |
| Multi-cat household (2 cats) | $300–$700 |
| Demodectic mange with underlying illness workup | $400–$900 |
| Severe or treatment-resistant case | $600–$1,200+ |
When It’s More Than Just Mange
Demodectic mange in adult cats is nearly always secondary to an underlying health problem. If your vet identifies Demodex cati, they’ll want to test for FIV, FeLV, diabetes, and hyperthyroidism — conditions that suppress immunity enough to let the mite population get out of control. Those workups add $200–$500 in bloodwork and diagnostics, but they’re important. Treating the mange while missing the underlying disease means you’ll be back at the vet again soon.
Saving Money Without Skimping
- Ask your vet about compounded topical selamectin — sometimes cheaper than brand-name Revolution
- Learn to apply lime sulfur dips at home after the first in-clinic session (your vet can show you)
- Treat all in-contact cats at once to avoid costly re-infestation cycles
- Some states have low-cost vet clinics run by humane societies that offer discounted skin condition workups
Frequently Asked Questions
Cat mange treatment typically costs between $150 and $800 depending on the type of mange and severity of the infestation. This range includes the initial veterinary exam ($75–$150), diagnostic testing like skin scrapings ($50–$100), and medication costs ($100–$600 for topical treatments or oral medications that may require multiple doses over 4–8 weeks.
Most pet insurance plans cover mange treatment as it is considered an illness rather than a pre-existing condition, though coverage varies by policy and provider. You can typically expect to pay 10–30% out-of-pocket after your deductible is met, with many plans covering 70–90% of eligible veterinary costs once the deductible ($250–$1,000) is satisfied.
Cat mange treatment usually takes 4–8 weeks depending on whether your cat has notoedric mange (highly contagious and faster-spreading) or demodectic mange (less contagious and slower to develop). Treatment typically involves weekly or bi-weekly topical applications or oral medications, with follow-up vet visits to confirm the mites are eliminated and prevent relapse.
