Circular bald patch with scaly edge on your dog's skin? Upload a close-up photo — AI identifies early stage ringworm vs classic round ringworm vs multiple lesions spreading vs crusty inflamed vs nail bed ringworm. ⚠️ Ringworm is CONTAGIOUS to humans and other pets — spores live in your home for up to 18 months. Isolate the dog and wear gloves until vet diagnosis confirms.

Part the fur around the suspected cat ringworm area so the lesion is clearly visible. Photograph from 2 angles — top-down + from the side — so the AI can see if it is early stage cat skin ringworm (1-2 small red round patches with subtle scaly edge, hair beginning to thin), classic ringworm ring pattern (circular bald patch with raised scaly edge + crusty center), severe / spreading multi-patch ringworm, or something mistaken for ringworm (miliary dermatitis or cat acne). Include 2-3 cm of surrounding healthy cat skin. Natural daylight, no flash.
The AI examines shape (circular ring = ringworm; scattered grain bumps = miliary; chin black dots = cat acne), edge (raised scaly = ringworm signature), location (face / ears / paws / back common for ringworm), and central pattern (crusty + central hair loss). It matches against known cat ringworm visual patterns and the most common look-alikes — the "what is mistaken for ringworm in cats" differential is the biggest value of this AI tool.
Receive the most-likely identification (cat ringworm early stage / classic ring / severe spreading / OR mistaken-for differential), urgency level (most ringworm = vet within a week for fungal culture; severe spreading kittens = vet within 48h), typical US vet visit cost estimate, zoonotic warning (ringworm is highly contagious to humans + other pets — gloves + bedding disinfection matters), and what diagnostic the vet will run (fungal culture is gold standard; Wood's lamp UV catches ~50% of strains).

1-2 small red round patches + subtle scaly raised edge + hair beginning to thin around the patch
Early stage cat skin ringworm — vet exam within a week for fungal culture confirmation. Catching ringworm early makes vet care easier
Circular bald patch + clearly raised scaly edge + crusty center + 1-3 cm across + on face / ears / paws / back
Classic ringworm cat skin pattern (dermatophytosis) — highly contagious to humans + other pets; vet fungal culture confirms (Wood's lamp UV catches only ~50%)
Multiple ringworm patches spreading across the body + kitten / immunocompromised / shelter cat + crusts forming
Severe / spreading ringworm cat skin — urgent vet visit within 48h; isolate from other pets and human family members
Many small grain-sized red bumps scattered along back / neck + NOT circular + intense scratching
Mistaken for ringworm: miliary dermatitis (usually flea allergy or food allergy) — different vet workup. See the cat-skin-rash tool
Black dots OR small bumps concentrated ONLY on the chin + NOT circular
Mistaken for ringworm: cat chin acne (comedones from plastic food bowls) — see the cat-acne-pictures tool for the chin-specific differential
Compare what you see on your cat's skin to known cat ringworm patterns. Upload your cat's skin photo above for AI analysis specific to your cat.



Cat ringworm pictures showing a small early-stage patch, a classic circular ring, or multiple spreading patches? Upload a close-up photo of the cat skin — the AI identifies early stage vs classic vs spreading ringworm AND rules out the most common look-alikes (miliary dermatitis, cat acne), tells you when to see a vet, gives a zoonotic contagion warning, and a typical US vet visit cost estimate.
