Endocrine and metabolic disorders may result in changes in the skin and hair coat. With regard to thyroid disorders, hyperthyroidism is the most common endocrinopathy in cats, whereas hypothyroidism is rare in this species. Diabetes mellitus is also a common feline endocrinopathy. Disorders of the adrenal cortex associated with changes of the skin and hair coat also occur in cats and not only are confined to hypersecretion of cortisol but also include hypersecretion of sex steroids. In addition to the dermatological changes observed in these endocrine disorders, the dermatological changes associated with metabolic disorders, i.e. superficial necrolytic dermatitis, xanthomatosis and acquired cutaneous fragility syndrome, will be presented.
