Neutering is one of the best decisions you can make for your cat's wellbeing. However, it causes hormonal changes that alter the metabolism: the cat needs fewer calories but retains the same appetite, which can lead to weight gain if the diet is not adjusted.
Why does the neutered cat put on weight?
After neutering, the cat's energy requirements decrease by 20 to 30%. Weight gain is associated with diabetes, joint problems and urinary conditions.
When to change the diet
The ideal is to switch to food for neutered cats in the weeks following the operation. If the cat is already overweight, the change must be made gradually under veterinary supervision.
What to look for in the food
High protein content: animal protein helps maintain muscle mass without excess calories. Look for chicken, turkey or salmon as the first ingredient.
Low or moderate in fat: reduces calories without sacrificing palatability.
L-carnitine: promotes fat metabolism and muscle maintenance.
Low in carbohydrates: cats are obligate carnivores. Excess carbohydrates contribute to weight gain.
Urinary pH control: neutered cats are more predisposed to urinary problems.
How much should it eat?
Neutered cats need 20–30% fewer calories. Divide the food into two or three meals a day.
Wet vs. dry food
Wet food provides hydration, important for preventing urinary problems. A combination of wet and dry can be a good strategy.
