Ringworm (dermatophytosis) is a highly contagious fungal infection affecting cats, particularly kittens and shelter populations. Treatment is prolonged and welfare implications are significant.
Ringworm causes discomfort through skin irritation and pruritus (itching), and can spread rapidly in multi-cat households and shelter environments. The prolonged treatment period — often 6-12 weeks — creates welfare challenges including isolation, repeated handling for topical treatments, and the stress of repeated veterinary contact. In shelter settings, ringworm is a major cause of extended stays and euthanasia. Welfare-centred management involves effective pain and itch relief alongside treatment, minimising isolation through compatible housing with other infected cats, and clear protocols to resolve infections quickly.
