Diabetes mellitus in cats is increasingly common and highly manageable. Appropriate management transforms welfare outcomes for diabetic cats and their owners.
Poorly controlled diabetes causes chronic suffering: weakness, weight loss, lethargy, peripheral neuropathy and susceptibility to secondary infections. Well-managed diabetic cats live comfortably with normal quality of life. The key welfare challenge is the transition period when the correct insulin dose is being established - hypoglycaemia episodes cause acute distress and require emergency response. Owner education, home glucose monitoring and regular veterinary monitoring enable safe and effective management. The prospect of remission is a significant welfare motivator: achieving dietary and weight control alongside insulin can eliminate the need for ongoing injections.
