Diet and Nutrition for Diabetic Cats

My cat has diabetes - what should I feed it?

Cats are obligate carnivores, meaning their natural diet consists primarily of animal proteins and fats, with minimal carbohydrates. This physiological characteristic significantly influences how diabetic cats should be fed. Unlike humans and some other animals, cats have limited carbohydrate metabolism, making them particularly sensitive to dietary sugars and starches. Proper diet management can improve insulin sensitivity, stabilise blood glucose levels, and reduce the risk of diabetic complications.

Nutritional Components for Diabetic Cat

Nutritional components for diabetic cats

High protein: A high-protein diet is fundamental in managing cat diabetes. Protein helps maintain muscle mass and provides sustained energy without spiking blood glucose levels. Studies suggest that feeding diabetic cats a diet with at least 40-50% protein on a dry matter basis can help manage blood sugar levels more effectively.

Low carbohydrate: Cats with diabetes benefit from a diet low in carbohydrates, typically less than 10% on a dry matter basis. Carbohydrates are rapidly converted to glucose in the bloodstream, which can cause significant fluctuations in blood sugar levels in diabetic cats. A low-carbohydrate diet minimises these fluctuations, making blood glucose easier to manage.

Moderate fats: While fats are an essential energy source, especially in carnivorous diets, the fat content should be moderate to avoid excessive calorie intake, which can lead to obesity. Balancing healthy fats and calorie control is vital for managing body weight and preventing further metabolic issues.

Fibre: Soluble and insoluble fibres can help regulate glucose absorption and improve gastrointestinal health in diabetic cats. Diets for diabetic cats that include moderate levels of fibre can aid in controlling postprandial (after-meal) blood sugar spikes. However, not all diabetic cats benefit from a high-fibre diet, and a veterinarian should assess individual needs.

Calorie control: Caloric intake should be closely monitored, especially for those who are overweight or obese. Weight loss in obese cats can improve insulin sensitivity and overall glycemic control. Portion control and feeding frequency should be tailored to maintain optimal body weight and prevent fluctuations in blood sugar levels.

Feeding strategies for diabetic cat

Feeding strategies for diabetic cats

Consistency: Regular feeding schedules are advised, particularly for insulin therapy patients. Consistent meal timing helps synchronise insulin administration with nutrient absorption, reducing the risk of hypoglycemia or hyperglycemia. Most diabetic cats are fed two to three times daily, aligned with their insulin regimen.

Prescription diets: Veterinarians may recommend prescription diets formulated specifically for diabetic cats. These diets are carefully balanced to provide high protein, low carbohydrate, and appropriate fibre levels. Consulting with your veterinarian is advised.

Wet food vs. dry food: Wet food is often preferred over dry food because it generally contains fewer carbohydrates and more moisture. Increased moisture intake is beneficial for urinary tract health, which can be compromised in diabetic cats. Dry foods formulated for diabetic cats can still be used but should be chosen carefully to ensure low carbohydrate content.

Home-prepared diets: Some cat owners opt for home-prepared diets to control the specific ingredients and nutrient content of their diabetic cat’s food. However, these diets must be carefully formulated under veterinary supervision to ensure they meet all of the cat’s nutritional needs and do not inadvertently cause nutritional deficiencies.

Monitoring and adjustments: Ongoing monitoring of blood glucose levels, body weight, and overall health is essential in managing diabetes in cats. Adjustments to the diet may be necessary based on the cat’s response to treatment, changes in body weight, or alterations in insulin sensitivity.

Diet and nutrition are integral components of managing diabetes in cats. A high-protein, low-carbohydrate diet, consistent meal timing, and careful calorie control can help stabilise blood glucose levels and improve a cat’s overall quality of life. Whether using prescription diets, wet food, or carefully prepared home diets, the key is to work closely with a veterinarian to tailor a dietary plan that meets the specific needs of a diabetic cat. Through proper diet management and regular monitoring, diabetic cats can achieve better health outcomes and lead more comfortable, stable lives.

Patient Stories

Our commitment to feline health is best seen in the stories of the cats we’ve had the privilege of treating. These journeys highlight the dedication, expertise and compassion that drive us.

Each patient faced unique challenges, and it was our honour to offer high-quality care and help them regain strength and happiness. We value the deep bonds with cats and their owners, knowing the difference we make in their lives.

Tango Triumphs Over FIP

At 5 months old, Tango was diagnosed with Feline Infectious Peritonitis (FIP). Once considered a fatal disease, the introduction of new treatments has significantly boosted the survival rate.

Toffee Survives Tick Paralysis

Toffee faced a frightening battle with tick paralysis and aspiration pneumonia, she was rushed to AES when her owners noticed her vomiting, breathing difficulties and trouble walking.

JJ & the Lily – a close call

Mischievous JJ had a close call when he ingested part of a lily—an extremely toxic plant for cats. Thanks to the quick actions of his owner, Sophie, a VSS vet nurse, JJ made a full recovery.

Han’s Hip Fracture Surgery

Han presented after limping on his hind leg for two weeks following an accident at home. An X-ray revealed a fractured growth plate in his hip, requiring surgery to repair the injury.

Coco and Kidney Troubles

Coco stayed with us at CSS while recovering from a nephrectomy (the surgical kidney removal). After months of unsuccessful treatment for a ureteral obstruction, this became necessary.
