Recognising and Managing Hypoglycemia in Diabetic Cats

Recognising and managing hypoglycemia in diabetic cats

If your cat receives too much insulin, their blood glucose level can drop dangerously low, a condition known as hypoglycemia (from the Greek “hypo” = low and “glycemia” = glucose in the blood). Hypoglycemia is a medical emergency that can have serious consequences if not promptly addressed. Understanding the signs and knowing how to respond can help prevent life-threatening complications.

Signs of Hypoglycemia in Cats

Signs of hypoglycemia in cats

One of the earliest signs of hypoglycemia is general weakness. A previously active cat may suddenly appear lethargic, unwilling to move, or weak in the legs.

As hypoglycemia progresses, cats may show signs of confusion or disorientation. They may exhibit behaviours such as:

  • Star-gazing: Staring blankly into space without responding to stimuli.
  • Bumping into objects: Your cat may accidentally run into furniture or walls due to impaired vision or disorientation.
  • Staggering or drunken walking: Cats may appear uncoordinated, with a wobbly or staggering gait resembling drunkenness.

In more severe cases, the cat may lose consciousness or collapse because its brain cannot function properly without glucose, its primary energy source.

If hypoglycemia is not treated promptly, it can lead to seizures or a comatose state. These are signs of critically low blood sugar and require immediate veterinary intervention.

Hypoglycemia in Cats

You must respond quickly

Prompt action is crucial if your cat shows any signs of hypoglycemia. Seeking veterinary attention immediately is essential, as untreated hypoglycemia can result in permanent brain damage or death.

While waiting to reach your vet, you can take steps at home to temporarily raise your cat’s blood sugar levels.

Having glucose syrup or powder available (easily obtained from most pharmacies) is a practical solution. These can be quickly absorbed through the mucous membranes of the mouth, raising blood glucose levels.

If glucose syrup is not available, honey can also be used.

These sugars are rapidly absorbed and can temporarily help stabilise your cat’s blood glucose levels while you seek veterinary care. Apply a small amount (about 1/2 teaspoon) of honey or syrup to the gums or tongue of your cat.

You may need to repeat this process every 5-10 minutes while transporting your cat to the vet, particularly if their condition does not improve. However, it’s crucial not to give excessive amounts of sugar, as this can lead to rebound hyperglycemia (high blood sugar), complicating treatment.

Preventing hypoglycemia

One of the best ways to prevent hypoglycemia is by regularly monitoring your cat’s blood glucose levels through home glucose meters or at the vet clinic. Understanding your cat’s typical blood sugar patterns will help you identify unusual fluctuations early.

Hypoglycemia is most commonly caused by overdosing on insulin. It is crucial to ensure that the correct insulin dose is administered based on your veterinarian’s instructions. Periodic reassessments of insulin needs, especially as your cat’s condition changes, can prevent dosing errors.

Make sure your cat eats a balanced meal before receiving an insulin injection. Skipping meals or significantly reducing food intake without adjusting insulin doses can increase the risk of hypoglycemia. Cats on insulin should be fed consistently, with careful attention to portion size, to ensure stable blood glucose levels throughout the day.

Illness, weight loss, or changes in activity level can affect how your cat responds to insulin. These factors may necessitate changes in insulin dosage. Keep in close communication with your vet to make timely adjustments to your cat’s treatment plan.

Long-term management

Understanding and preventing hypoglycemia is an integral part of managing a diabetic cat.

In addition to being prepared with emergency glucose sources, owners should focus on routine health checkups and blood glucose monitoring.

Regular veterinary consultations can help adjust insulin doses as needed, taking into account fluctuations in your cat’s overall health, weight, and activity level.
