Why Is My Elderly Cat Pulling Her Fur Out?

Hyperthyroidism, alopecia, cancer, heart disease, and diabetes are among the illnesses that can induce fur pulling. Fleas, lice, ticks, and skin mites are among the skin parasites that can cause itchy skin in humans and animals. In the case of an elderly cat that tears out his or her hair, the most likely cause is arthritic discomfort, hyperthyroidism, or nutritional inadequacies.
