Cat Ringworm: Fungal Disease Welfare

Ringworm (dermatophytosis) in cats causes skin discomfort and is a common reason for shelter relinquishment, with welfare implications for affected animals.

Key Facts

Ringworm is a fungal infection caused by Microsporum canis, not a worm
It causes hair loss, scaling, and variable pruritus in affected cats
Ringworm is highly contagious to other cats and to humans, complicating management
Antifungal treatment including lime sulfur dips and oral medication is effective but requires persistence

Welfare Considerations

Ringworm causes skin discomfort and significantly affects the welfare of cats in shelter settings, where it is a leading cause of extended stays and euthanasia. Effective treatment protocols and biosecurity measures can reduce welfare impacts on affected animals.

What You Can Do

Seek veterinary treatment promptly if your cat shows signs of ringworm
Support animal shelters developing effective ringworm management protocols
Advocate for ringworm to be treated as a treatable condition rather than a reason for euthanasia in shelter settings
