Ketones in Diabetic Dogs and Cats: Why They Matter
What ketones mean in diabetic dogs and cats, how ketoacidosis develops, and why some cats can be seriously unwell despite a normal glucose reading.
Ketones in diabetic dogs and cats: why they matter
Important: If your pet is vomiting, refusing food, very lethargic, or seems unwell, contact your vet immediately — even if their glucose reading looks fine.
Quick answer
Ketones build up when the body cannot use glucose normally and starts breaking down fat. A dangerous build-up can lead to diabetic ketoacidosis (DKA), an emergency. Cats taking oral SGLT2 medicines such as Senvelgo or Bexacat can develop ketoacidosis while their glucose reading looks normal, so a reassuring number does not rule out a problem.
What ketones are
Ketones are produced when the body turns to fat for energy. Small amounts may prompt monitoring, but rising ketones alongside illness, food refusal or dehydration need urgent veterinary advice.
What ketoacidosis means
DKA is a serious metabolic emergency rather than simply a high glucose reading. Vomiting, dehydration, unusual breathing, marked lethargy and refusal to eat are warning signs. Do not wait for a routine appointment.
How testing works
Ketones may be checked with urine strips or a blood ketone meter at home, or with veterinary testing. Ask your vet which method is appropriate and what result or symptom should trigger a call.
When to contact your vet
Contact your vet immediately if your pet is vomiting, refusing food, very lethargic, dehydrated or simply seems unwell. This is particularly important for cats taking SGLT2 medicines. For low blood sugar guidance, read the hypoglycaemia guide; for a wider emergency reference, use diabetic pet emergencies.
Mello helps you keep a clear record to share with your vet. It does not diagnose ketoacidosis or interpret ketone results.
When to contact your vet
- Contact your vet promptly if your pet’s symptoms, appetite, drinking, urination, behaviour or glucose readings change unexpectedly.
- Ask your vet for advice before changing insulin, food, exercise or any other part of your pet’s routine.
- Seek urgent veterinary care for collapse, seizures, severe weakness, repeated vomiting, or suspected hypoglycaemia or diabetic ketoacidosis.
