In brief
Treatment combines insulin or another veterinarian-selected therapy, suitable nutrition, weight management and reliable monitoring. The aim is a cat that feels well—not a perfect number at every measurement.
The treatment plan
Many cats need insulin injections, usually twice daily. Modern options also include oral SGLT2 inhibitors for carefully selected cats, but these are not suitable for every patient and require specific safety screening. Your veterinarian will choose treatment based on the cat’s health, ketone risk and household circumstances.
Nutrition and body weight
A consistent, complete diet that supports a healthy body weight is important. Wet food can help water intake and lower-carbohydrate diets may benefit some cats, but eating reliably is more important than forcing a theoretically perfect diet. Weight loss in an overweight cat should be gradual and supervised.
Monitoring at home
- Record appetite, water intake, urine output, body weight and insulin doses.
- Home blood-glucose curves or continuous glucose monitors can reduce stress-related distortion.
- Never change a dose based on one isolated value unless your veterinarian has given a specific protocol.
- Check ketones when advised, particularly if appetite falls or the cat becomes unwell.
Hypoglycaemia
Weakness, tremors, disorientation, seizures or collapse can indicate dangerously low blood glucose. Offer food if the cat is able to swallow and contact a veterinarian urgently. Do not give the usual insulin dose to a cat that is not eating unless specifically instructed.
Remission
Some cats no longer need insulin after early, effective control and correction of insulin resistance. Remission still requires follow-up because diabetes can recur.
Conclusion
Successful treatment is a partnership. A realistic routine, good communication and attention to how the cat feels are more valuable than chasing flawless glucose values.
