Brit GF Veterinary Diet Diabetes Cat, 400 g is a grain-free dietetic food from the Czech brand Brit for cats with diabetes mellitus, hyperglycaemia and excess weight. Its key features are very high protein (46%) from dehydrated chicken (48% of the recipe) and low carbohydrates: 15% starch and just 0.8% simple sugars, which reduces glucose spikes after meals. Psyllium and bamboo fibre add satiety. Energy: 374 kcal per 100 g.
What it is and who makes it
Brit is a Czech brand with a Veterinary Diet range. Diabetes Cat is designed for glucose control in cats. Cats are obligate carnivores whose metabolism runs on protein and fat rather than carbohydrates, so a high-protein, low-starch diet matters especially in diabetes. The course is up to 6 months, as prescribed by a vet.

How to feed a diabetic cat
Consult a vet before starting and before extending the course. Feed dry or softened with warm water. Per the instructions, the cat should have access to its daily portion and fresh water through the day. Weigh the portion precisely on scales and don't top it up. Agree on meal and insulin timing with your vet. Cut out treats and table food, as they upset blood sugar. More on routines in how many times a day to feed a cat.
Signs of diabetes in cats
The cat drinks and urinates a lot (the litter gets wet quickly), loses weight despite a good appetite, becomes lethargic, and sometimes starts walking on its hocks with the hind legs. Middle-aged and older overweight neutered males are affected most often. Blood and urine tests confirm diabetes. More on older cats' health in senior cat nutrition and care.
Hypoglycaemia risk and the role of weight
A high-protein diet lowers insulin needs, so a dose set on the old food may become too high after the switch. Signs of hypoglycaemia — trembling, wobbliness, weakness, seizures — need urgent help. Excess weight reduces insulin sensitivity, so gradual weight loss makes diabetes easier to control. With proper treatment some cats can go into remission, which the vet assesses with tests. More in overweight cats and dogs.
Who it suits
Adult cats with diabetes mellitus, hyperglycaemia and excess weight, as prescribed by a vet. For weight loss without diabetes there's Brit VD Obesity Cat, and for diabetic dogs Brit VD Diabetes Dog. Other therapeutic foods are in veterinary diets for cats.
Verdict
Brit Veterinary Diet Diabetes Cat is a grain-free, high-protein diet with minimal sugars and starch for diabetic and overweight cats. It suits the cat's carnivorous nature but works together with insulin, precise portions and regular glucose monitoring.
