Scabies in cats appears as thick, yellowish-gray crusts and scales, typically starting on the ears and face before spreading outward. The affected skin loses its fur, turns red, and becomes intensely itchy. Unlike many other skin conditions in cats, scabies has a very recognizable pattern: it almost always begins on the head and works its way down the body.
What Causes Scabies in Cats
Feline scabies is caused by a microscopic burrowing mite called Notoedres cati. This is a different species from the mite that causes scabies in dogs or humans. The mites are tiny enough that you won’t see them with the naked eye. They tunnel into the outer layer of your cat’s skin, laying eggs as they go, which triggers an intense immune response and the visible skin damage you’ll notice.
Cats pick up the mite through direct contact with an infested animal. It spreads easily between cats in the same household, and outdoor cats are at higher risk from encounters with strays or wildlife.
Early Signs on the Ears and Face
The first place to look is the ears. Scabies in cats nearly always starts at the ear margins, the thin edges of the ear flaps. You’ll notice the skin there becoming crusty, flaky, and bare. The fur thins or falls out entirely, and the exposed skin looks red and irritated underneath the crusts.
From the ears, the crusting spreads across the face. The skin around the eyes, forehead, and bridge of the nose develops the same thick, scaly texture. At this early stage, people sometimes mistake it for a bad case of ear mites or ringworm. The key difference is the severity of the crusting and the relentless scratching. Cats with scabies itch far more intensely than with most other skin conditions, often scratching until they create raw, bleeding patches.
How It Spreads Across the Body
Left untreated, scabies does not stay confined to the head. The crusty, hairless patches spread down the neck, onto the chest, legs, and eventually the belly. One clinical description of advanced cases notes eczema-like lesions covering the face, ear margins, legs, chest, and lower abdomen. In the worst cases, the disease covers the entire body.
As the infestation progresses, the skin changes become more dramatic. The crusts thicken and layer on top of each other, giving the skin a rough, almost bark-like texture. The skin underneath may darken and thicken from chronic inflammation. Cats at this stage often look visibly unwell: thin, unkempt, with large patches of missing fur replaced by gray-yellow scabs. The constant scratching and skin damage can also open the door to secondary bacterial infections, which add oozing, swelling, or a foul smell to the picture.
How Vets Confirm the Diagnosis
A veterinarian will suspect scabies based on the appearance and location of the lesions, but a definitive diagnosis comes from a skin scraping. This involves gently scraping the surface of the crusty skin with a blade, placing the collected material on a glass slide, and examining it under a microscope. The mites, their eggs, and their waste products are usually visible in the sample. Because the mites are abundant in most feline cases (more so than in dogs with sarcoptic mange), skin scrapings tend to be reliable.
What Treatment Looks Like
Feline scabies is very treatable. Most vets prescribe a topical anti-parasitic medication applied to the skin between the shoulder blades. In clinical studies, cats treated with a single topical dose were completely free of mites within 30 days. The skin itself takes a bit longer to heal. Crusting, redness, and hair loss typically resolve fully within about 60 days of starting treatment.
All cats in the household need treatment, even those not yet showing symptoms, since the mite spreads through direct contact and an infested cat can pass it along before visible signs appear. Bedding and resting areas should be washed thoroughly, though the mites don’t survive long off a host.
Can You Catch It From Your Cat
Yes, but with an important caveat. Notoedres cati can temporarily infest human skin, causing itchy red bumps most commonly on the hands and legs. The itching can start within hours of contact with an infested cat. However, this mite cannot complete its life cycle on human skin, so the rash is self-limiting. Once the cat is treated and separated from close contact during recovery, the human symptoms clear up on their own without specific treatment. This temporary reaction is sometimes called pseudoscabies.
If you’re handling a cat you suspect has scabies, wearing gloves and washing your hands and arms thoroughly afterward reduces the chance of a reaction. But the most effective solution is simply getting the cat treated promptly.
