Managing Diabetes in Cats: Welfare and Quality of Life

Feline diabetes mellitus is a common endocrine disorder in middle-aged and older cats. With proper management including dietary change and insulin therapy, many diabetic cats achieve remission and good quality of life.

Key Facts

Approximately 1 in 100 to 500 cats develops diabetes mellitus during their lifetime
Obesity is the most significant modifiable risk factor for feline diabetes
Type 2 diabetes (insulin resistance) is most common in cats, unlike the Type 1 typically seen in diabetic dogs
A high-protein, low-carbohydrate wet food diet can significantly improve glycaemic control
Remission — sustained normal blood glucose without insulin — occurs in 25 to 60% of well-managed cats
Twice-daily insulin injections are typically required, often given by owners at home
Uncontrolled diabetes leads to weight loss, lethargy, peripheral neuropathy, and ketoacidosis

Welfare Considerations

Cats with poorly controlled diabetes suffer from polyuria, polydipsia, muscle wasting, and progressive neuropathy that can cause a plantigrade stance. Good welfare depends on consistent glucose monitoring, appropriate insulin dosing, and dietary management. Hypoglycaemia from insulin overdose is an acute welfare emergency. With committed owner management, diabetic cats can maintain excellent quality of life and many achieve full remission, eliminating the need for ongoing insulin therapy.

What You Can Do

Prevent feline diabetes by keeping cats at a healthy weight with appropriate diet and regular exercise
If your cat is diagnosed, work with a veterinarian experienced in feline endocrinology
Learn to monitor blood glucose at home using a validated feline glucometer
Feed a high-protein, low-carbohydrate diet as recommended by your veterinarian
Support research into feline diabetes prevention and treatment through veterinary school donations
