Do I Need a Prescription Cat Diet?

Veterinarians commonly recommend prescription diabetic foods and, although most cats will do very well on these foods, some have more than 10% of carbohydrates in them and are not ideal for all cats.

Prescription diets are not necessary to successfully manage a diabetic cat’s diet. Many commercial cat foods are appropriate for diabetic management as they contain less than 10% carbohydrates in them. It is important to find the best diabetic cat food you can.

In many cases of feline diabetes, diet alone can be an effective way to manage it and trigger remission, with many cats not requiring medication after switching to a low-carb diet.

A diet high in carbohydrates increases blood glucose and insulin, which results in diabetes and obesity if not properly managed. So, with that in mind, here are our picks for the best diabetic cat food you can buy today.

Feline Diabetes

Cats truly are a handful, that’s for sure, but we love them anyway. Unfortunately, some owners find out that their kitty has developed feline diabetes and have to take extra measures to make sure their cat remains fit and healthy.

Feline diabetes is similar to human type-2 diabetes; insulin resistance with a lower insulin production rate. It typically effects middle-aged and elderly cats and is more common in male cats than female. It is also more likely to develop in cats who are overweight or live a less active lifestyle.

The signs of feline diabetes, just like human diabetes, are caused by having blood glucose levels which are too high. If your kitty is urinating a lot, it could be a sign of diabetes as the kidneys will be working harder to remove glucose from the blood. If your cat displays abnormal eating or peeing a lot, or any odd behaviour in general, it is always best to take a trip to the vet.

Can Feline Diabetes Be Cured?

This depends entirely on your individual cat. IF you start treating your cat’s diabetes early and get their blood sugar under control through a reasonable, tailored diet, and get their body in a better condition – such as helping your kitty lose weight – then diabetes can sometimes go into remission.

However, diabetes is controlled and is not usually cured. Your kitty can go into remission and remain in such a state for many months or even years. For the most part, though, your kitty’s diabetes will simply be in a controlled state and could come back if your cat gets back onto a bad diet or if bad habits make a return.

Will Diabetes Shorten My Cat’s Life?

It can, especially if it is left untreated and uncontrolled. Diabetes can be associated with infections and other problems. If diabetes is poorly controlled, your kitty can develop some pretty nasty health complications.

With appropriate management, a cat can live a long and normal lifestyle, even with diabetes. Having a diabetic cat does require a lifelong and daily commitment from you though, as your cat cannot manage his or her diabetes alone; it is all part of being a loving and doting kitty owner.

What Type of Food Would You Recommend?

As you may be aware, cats are obligate carnivores. This means that your kitty needs meat, it is not an option, and they have a high dietary protein requirement. In fact, you could opt to feed your kitty completely on protein without any carbohydrates at all.

A cat’s digestive system is designed for foods which are high in protein, moderate in fat and low in carbohydrates. An ideal feline diet looks like this –

  • 50% or more calories from protein
  • 20-40% of calories from fat
  • 1% of calories from carbohydrates
  • Moisture-rich

So, if you’ve got a diabetic cat, it is crucial that you hit the nail on the head with these dietary requirements and invest the best diabetic cat food.

This composition of protein, fat, carbohydrates and water will only be found in wet, canned food. Most dry foods are high in carbohydrates and do not have a high enough protein level to satisfy a cat’s protein requirements. So, dry foods are generally not recommended for diabetic cats.

It is widely known that an ideal diet for a diabetic feline – especially to achieve remission – is high-protein, low-carbohydrate, canned wet food.

When faced with a diabetic kitty, the two most important goals for you are –

  • Get your cat on a low carb diet as soon as possible; and
  • Learn how to home-test your cat’s blood sugar levels.

If you change your diabetic kitty’s diet to one with less carbohydrates (i.e. immediately swap out dry food for wet food) your cat will probably require an immediate reduction in his or her insulin dosage.

A diet which is low in carbohydrates provides under 10% of your kitty’s total calories as carbohydrates. Generally speaking, the less carbohydrates the better feline diabetes is managed.

Transitioning Between Food

This is the most difficult aspect of helping a kitty with diabetes. The cat must find his or her new food palatable in-order for it to be successful, and it is hugely important that a diabetic cat does not miss meals; a diabetic cat must consistently eat the same type and amount of food each day to regulate diabetes.

If your kitty does not like his or her new food, you will need to get something else. It’s irritating, but it must be done. If your cat has always eaten dry food and not eaten much wet food, this can be even more challenging. To switch your cat from dry to wet food, try following some of these tips –

1) Stop ‘free feeding’ your cat and establish meal times. Cats who are used to having dry food available all day may be unwilling to try new food because they are usually not hungry when they graze on dry food all day.

2) At meal times, offer canned food in addition to dry food and leave it there for only 30 minutes, then remove the uneaten food.

3) If your kitty is still refusing dry food, gradually decrease the amount of dry food and offer wet food in its place. Natural hunger will soon take over and your kitty will eat it.

There are lots of ways you can make your kitty’s wet food more appealing, too –

  • Mix a little wet food and dry food together for a gradual transition.
  • Try different brands and flavours until your cat accepts one.
  • Attempt to hand-feed the canned food.
  • Exercise your cat prior to eating or pet your cat at the food bowl.
  • Try putting meat or fish on top of the food to entice your cat more.

If you still struggle to move your cat onto a wet canned food diet, don’t fret; there are plenty of dry foods specially formulated for diabetic cats.

The Round Up

Diabetes is quite rare in cats, with around 2% of the American feline population suffering from it. If you do get the unfortunate news that your kitty has developed a case of feline diabetes, do not be too alarmed – it is completely manageable with a good diet and proper routine, and many cats go into remission after proper treatment. It cannot be cured, however, and owning a diabetic kitty is a lifelong commitment.

There are plenty of brilliant non-prescription foods on the market which are high in protein and low in carbohydrates, which is exactly the kind of diet a diabetic cat should be on in-order for the best chances of remission.

Have you ever looked at Young Again Pet Food for cats? I have turned two diabetic cats completely around with their 0 carb dry food because I had a diabetic cat that would not eat wet food. You may want to look at this?
