Symptoms of Cushing's Disease in Cats

Cushing's disease develops in cats because the adrenal gland produces too much of the hormone cortisol. In most cases the gland malfunctions because of a pituitary tumor, but another possible cause is a tumor on the adrenal cortex. Both medicinal and surgical treatments are available for cats with Cushing's disease. The most effective treatment is typically surgical removal of both of the cat's adrenal glands.

  1. Increased Thirst

    • One of the most common signs of a cat with Cushing's disease is an increase in thirst and a subsequent increase in urination. Some cats may also develop a larger appetite when the condition develops. All three of these are also symptoms of diabetes, and in many cases cats will have both conditions.

    Skin and Fur

    • Cats with Cushing's disease will typically have more fragile skin than previously. It may tear or bruise easily and take a long time to heal. Symmetrical hair loss is also a common symptom.

    Weight Gain

    • Weight gain is common in cats with Cushing's, but in some cases unexplained weight loss can also be a sign of the condition. Cats that gain weight may develop a potbelly or begin to carry their excess weight in the abdomen.

    Other Symptoms

    • Cats that develop Cushing's disease may also exhibit some of the following common signs of the condition: increased lethargy or fatigue; recurrent illnesses or infections; muscle weakness or wasting; and decreased attention to grooming.
