What is cat diabetes?

When a cat has diabetes, it means their pancreas isn’t producing enough insulin. Or it could mean their body isn’t responding to insulin properly which is called insulin resistance. Insulin is needed to help absorb sugar from the bloodstream into cells around the body, giving your cat energy.  

Cats with diabetes struggle to control their glucose levels in the bloodstream, so they can suffer from dangerously high spikes of sugar called hyperglycaemia. Diabetic cats may also have to use muscle or fat for energy as the sugar isn’t getting where it needs to be. This process can create dangerous by-products called ketones.

How do cats get diabetes?

Type 2 diabetes is more common than type 1 diabetes in cats.  

  • Type 2 diabetes is caused by problems with the pancreas, causing either a reduction or resistance to insulin.  
  • Type 1 diabetes is when the body destroys the cells that produce insulin in the pancreas. 

Male cats are more likely to develop diabetes. Other risk factors include obesity, age, inactivity, and using steroids to treat other conditions. 

What Causes What Causes
Which breeds are most affected?

Any cat can develop diabetes, but some breeds are more likely to get it than others, including: 

  • Burmese 
  • Norwegian Forest 
  • Tonkinese
  • Siamese 

Risk factors are mainly due to genetic predisposition, body composition and lifestyle.

Certain breeds, especially Burmese and Siamese cats, have been shown to have a higher genetic risk for diabetes. Likewise, Burmese and Norwegian Forest Cats tend to have a stockier build and can be prone to obesity, a key risk factor for diabetes.  

But while genetics play a role, diet and exercise also influence diabetes risk – regardless of your cat’s breed. 

What Causes What Causes
What are the signs and symptoms of diabetes?

The most common signs and symptoms to watch out for include: 

  • increased urination 
  • excessive thirst 
  • increased appetite 
  • weight loss 

Some other symptoms you may spot include: 

  • lethargy 
  • vomiting and diarrhoea 
  • sunken back legs 
  • increased risk of other diseases, including infections and pancreatitis

Diagnosis and treatment of cat diabetes

If you think your cat might have diabetes, speak to your vet. They’ll be able to do a few tests to see how likely it is, including urine samples and blood tests to see if sugar levels are high.  

Cats can have high glucose levels when stressed, such as during a vet trip. Your vet may need to perform an additional blood test called fructosamine. This acts as a marker of blood glucose over the previous few weeks. They may also want to take glucose measurements over the course of a day.       

Treatment options

There are two main diabetes treatment options that are often used together to get the best results.  

Insulin injections 

Most cats with diabetes will need insulin injections once or twice a day, usually just after they eat. Your vet will show you how to use the injections, usually in the scruff of their neck. 

Routine is important, with meals and injections given at the same time each day where possible. There are different types of injections, so you can discuss with your vet which option would be best for your cat.   

When controlled with insulin injections, your cat shouldn’t have any symptoms of diabetes, and if caught early enough, can even become non-diabetic. 

Diet 

Diabetic cats need a special diet to make sure they keep their weight down and their glucose levels controlled. Your vet will be able to advise you of the best steps to take.  

What Causes What Causes
Can my cat recover from diabetes?

Diabetes can often be a lifelong condition for cats. But caught early enough and with the right treatment, theres the possibility of reversing it altogether in some cats. Sadly, there are some cats who don’t respond well to treatment for a variety of reasons.

Frequently asked questions about diabetes in cats

  • Does diabetes cause strange behaviour in cats? 

    Some people find that their cat walks strangely before their diagnosis. This is because the nerves can sometimes get damaged which causes your cat to walk on their ankles instead. Diabetic cats may also be lethargic and sleep more than usual. 

  • Can you treat cat diabetes without insulin? 

    Most diabetic cats will need some form of insulin. If caught early enough, it may be manageable with diet-only treatment, or they can come off insulin injections after an initial treatment.  

    But this is something to chat to your vet about, as every cat is different and some respond to treatment better than others.   

  • What’s the life expectancy for cats with diabetes? 

    With the appropriate treatment, your cat could live a long and happy life after their diabetes diagnosis. Sadly, sometimes treatment isn’t an option or your cat might not respond well to it.
