Diabetes in Dogs and Cats
Just like in people, diabetes in dogs and cats is a serious condition that requires lifelong management—but with the right care, pets with diabetes can live happy, comfortable lives. Early recognition and treatment make a big difference, so it’s important to know what signs to look for and how the condition is managed.
In this blog, we’ll cover what diabetes is, which pets are most at risk, how it’s diagnosed, and how you can help your pet thrive.
What is Diabetes?
Diabetes mellitus occurs when the body is no longer able to regulate blood sugar (glucose) levels properly—either because it doesn’t produce enough insulin or because the cells no longer respond to it. The result is too much sugar in the blood, which can have damaging effects throughout the body if left untreated.
There are two types:
- Type I (insulin-dependent) – more common in dogs
- Type II (non-insulin dependent) – more common in cats, though many still need insulin eventually
Signs of Diabetes in Pets
If you notice any of the following signs in your pet, book a vet check-up:
- Increased thirst and urination
- Weight loss despite a normal or increased appetite
- Lethargy or weakness
- Cloudy eyes in dogs
- Poor coat condition in cats
- Urinary tract infections
- Vomiting or collapse in advanced cases
Book a diagnostic consult here if you’re concerned your pet may have diabetes.
What Causes Diabetes in Pets?
Risk factors include:
- Age – more common in middle-aged and older pets
- Obesity – especially in cats
- Chronic pancreatitis – especially in Miniature Schnauzers
- Hormonal conditions like Cushing’s disease
- Certain medications (e.g. long-term steroid use)
- Breed predispositions: e.g. Poodles, Dachshunds, Burmese cats
How We Diagnose Diabetes
Diagnosis involves a combination of:
- Blood tests – showing elevated glucose
- Urinalysis – detecting glucose or ketones in urine
- Further lab work to rule out complications
Once diagnosed, your vet will discuss a treatment and monitoring plan tailored to your pet’s needs.

Treating Diabetes in Dogs and Cats
Management usually includes:
- Insulin injections – typically twice daily for dogs and most diabetic cats
- Diet change – prescription diets to stabilise blood sugar
- Routine – keeping meals and insulin on a strict schedule
- Monitoring – either at the clinic or at home using blood glucose curves or glucose sensors
We’ll teach you how to administer insulin safely and support you throughout your pet’s diabetes journey.
Can Diabetes Be Prevented?
While some pets develop diabetes due to genetics or other health problems, prevention is possible in many cases—especially in cats.
Tips include:
- Keeping pets at a healthy weight
- Feeding balanced, vet-recommended diets
- Treating pancreatitis and hormone disorders early
- Regular vet check-ups to catch early signs
