What is Diabetes in Cats?

Cats’ Diabetes, commonly called Feline Diabetes, is a medical condition that takes place when the insulin within your pet’s body can’t be produced or handled correctly. The job of insulin is to assist the body in the digestion of glucose (sugar) after it has been eaten. If your cat has insufficient or ineffective insulin levels, it will most probably result in high sugar levels in the blood of your pet. This is the reason why your cat’s diet demands your immediate attention.

How to Choose Healthy Food for Your Diabetic Cat?

Deciding on the most appropriate diet for your diabetic feline can be a tough job, but it is far from impossible. To guide you in the process of buying food for your pet, here are some tips to help you:

  • Low-Carb Diets: Diabetic cats should eat food with a low carbohydrate content. This is because carbs are converted into sugar, which can cause significant spikes in blood sugar levels. Such food should be the one that has low carbs and high protein.
  • High Protein: Cats are obligate carnivores, which basically means they must have protein in their diet to survive. Go for food that is rich in chicken, turkey or fish. Such food that contains these protein sources not only helps in protecting lean body mass but also activates the cat’s metabolism.
  • Moisture Content: Food that contains much water is not only beneficial in hydrating the feline but also in preventing dehydration, which is a common health issue for diabetic cats. It also has the benefit of kidney-boosting, which has become a major concern for diabetic cats.
  • Veterinary Recommendations: Always get the permission of your local veterinarian before subjecting your cat to a change in its diet. They can advise you on the brands or formulas of food that will be most suitable for your cat’s specific needs.
