Diabetic Cat Not Eating and Drink Water

Diabetes or diabetes milletus has been a common condition in humans. But did you know that this condition is not only exclusive to humans? Our feline friends are also capable of having this condition. Well this wouldn’t be news to fur parents who have cats with this condition, but if you are totally new to the condition, you might want to read on to better understand this condition in cats and help you answer why your diabetic cat is not eating and drinking water

Diabetes, what is it all about?

It can be really difficult to hear that our beloved feline friends are diagnosed with diabetes. While there is no known cure yet to completely eliminate the disease, be assured that it is manageable.

Diabetes is a lingering condition that recurs in the duration of the feline’s lifetime. It is a condition where a cat’s body is unable to produce enough insulin as needed or where a cat’s body does not respond to the insulin generated by its body.

Pretty familiar isn’t it? It’s really very much like the diabetes which humans experience. Insulin is central to understanding diabetes. It is an important hormone produced by the pancreas, which regulates blood sugar or glucose found in most of the food our cats eat that provides them with the energy that their body needs.

Symptoms of a Diabetic Cat

Now there are a lot of symptoms to watch out for that will tell you if your cat has diabetes.

If you notice that your cat exhibits these two symptoms, then it could mean something:

1. Frequents its litterbox more than usual to pee and

2. If you notice that your cat consumes more water than it usually does

These two symptoms alongside with lethargy, hunger, weight loss, vomiting and depression are some of the most common symptoms of diabetes in cats.

A Diabetic Cat Who Refuses to Eat

One important symptom to really watch out for is when your cat has a sudden change in appetite. Watch out if your cat is eating less or eating more than usual. A cat’s eating habit is key when it comes to managing diabetes. Why? This is due to the fact that the insulin shots you will give to your cat depends on its food intake. If your cat tends to eat less resulting to weight loss, you can endeavour to put back weight on to your cat or the key lies in adjusting the dosage of insulin it receives.

A diabetic cat that doesn’t want to eat may be an indication that there could be a possible complication that comes along with diabetes. These complications may include hypoglycaemia and diabetic ketoacidosis.


Hypoglycaemia is a condition where your cat gets too much insulin in relation to the calories in its food it is taking in. Diabetic ketoacidosis, on the other hand, is a condition where your cat’s metabolism is quite out of hand and it starts to metabolize its fat in order to generate energy. This scenario results to an accumulation of chemicals called ketones, this is the culprit that makes your cat feel sick.


Once your cat develops diabetic ketoacidosis, expect to see other symptoms like lethargy, lesser water intake and vomiting. You can check out your local store for low carb dry cat food that will be suitable for your cat.

Other difficulties that diabetic cats are vulnerable to, mainly concerns and complications in their organs. It may include urinary tract infection, kidney disease, dental disease, inflammation of the pancreas, liver or gall bladder, and inflammatory bowel disease.

A diabetic cat’s condition can become really delicate and would really require a great deal of attention especially when it comes to your cat’s eating habits and other behaviours.

What to do?

1. Balanced Diet – You have to make sure that your cat has a balanced diet. Now if your cat seems to have little to no appetite, you can ask your veterinarian for tips and advice on how to address this. Your vet will give you the appropriate diet regimen for your cat’s condition. As we have reiterated above, your cat’s diet is central to managing diabetes.

2. Learn – Do not be afraid of your cat’s condition. Read more about it and make an effort to learn about how to administer your cat’s meds and check its blood sugar levels.

Bottom Line

Diabetes in cats may be a disease that isn’t curable, but that doesn’t mean that we would easily give up. Dedication and love for our feline friends will keep you company in taking good care of them.
