Chinchilla Ringworm: Bald Patches, Treatment, and the Zoonosis Risk

A circular bald patch on a chinchilla's nose, ears or feet is often ringworm — a fungal infection, usually Trichophyton mentagrophytes, that spreads to people. Chinchillas can also carry it while looking completely healthy, so hand-washing and a vet-run culture matter more than how the patch looks.

Scratching, scabs and thinning fur in a gerbil are far more often nasal dermatitis, barbering or a fight wound than mites — and mites can only be confirmed with a microscope. Here is how the diagnosis is actually made and what to fix at home while you wait.

Hedgehog Dry, Flaky Skin: Dandruff, Mites, or Normal Quilling?

Dry, flaky skin on an African pygmy hedgehog is easy to miss under the quills and easy to misread. If the flaking comes with quill loss, it is mites until a veterinarian's skin scrape says otherwise — not something an oatmeal bath will fix.
