Common symptoms of diabetes in cats include: 

• Drinking more than usual  

• Passing urine more frequently 

• Weight loss despite eating normally or more than usual 

• Increased appetite 

• Poor coat condition 

• Weakness, especially in the back legs 

• Urinary tract infections - Cats with diabetes are more prone to urinary tract infections because higher levels of glucose in the urine can encourage bacterial growth. Signs may include: 

  -Urinating more 

  -Straining to urinate 

  -Blood in the urine 

  -Urinating outside the litter tray 

If you notice signs such as increased thirst, frequent urination, or unexplained weight loss, contact your vet for advice. Early diagnosis of diabetes in cats can make the condition easier to manage and may reduce the risk of complications. 

Your vet may diagnose diabetes using a combination of: 

• Your cat’s medical history and reported symptoms 

• A full physical examination 

• Blood tests to measure glucose levels 

• Urine tests to check for glucose or ketones 

Additional blood tests may sometimes be recommended to confirm the diagnosis or to check for other health conditions that can occur alongside diabetes.  

How diabetes is treated will depend on the individual cat and their overall health. 

• Insulin is the most common treatment for diabetes in cats. It is usually given as an injection under the skin, typically twice daily. Your vet or veterinary nurse will show you how to give these injections safely at home. Most cats tolerate insulin injections very well. 

• Oral therapies may be used to help manage diabetes in cats in some cases. These medications are not suitable for every cat, and your vet will advise whether this treatment option is appropriate.  

• Diet can play an important role in managing diabetes. Your vet may recommend a specific diet to help stabilise blood glucose levels and support weight management if your cat is overweight. 

• Regular monitoring is important to ensure treatment is working effectively. Your vet may recommend follow-up appointments and repeat blood or urine tests to check glucose levels and adjust treatment if needed. 

If diabetes is not well controlled, some complications can occur: 

• Diabetic ketoacidosis is a serious complication that can develop if diabetes is untreated or poorly controlled. Signs may include: 

  Vomiting 

  Loss of appetite 

  Severe lethargy 

  Collapse 

This is a medical emergency and requires urgent veterinary treatment. 

• Hypoglycaemia occurs when blood glucose levels drop too low, most often due to too much insulin. Signs may include: 

  Weakness 

  Disorientation 

  Collapse 

  Seizures 

If you notice these signs, contact your vet immediately. 

Not all cases of diabetes can be prevented, but the following steps may help reduce the risk: 

• Feeding a balanced diet that is high in protein and low in carbohydrates 

• Limiting treats 

• Monitoring your cat’s weight 

• Encouraging regular play and exercise to help maintain a healthy weight 

• Providing a stimulating environment with toys, scratching posts and climbing areas 

The long-term outlook for cats with diabetes varies depending on their age, how easily their diabetes can be stabilised, and whether they have any other health conditions. Many diabetic cats can have a good quality of life and live happily for years when their diabetes is well managed.
