Low Blood Sugar

Published on September 26th, 2024
Updated on October 22nd, 2025

SUMMARY OF CONTENT

Kitten hypoglycemia occurs when a kitten has low blood sugar.

SEVERITY:

Severity is moderate

  • Requires a diagnosis by a veterinarian
  • Resolves within hours after medical treatment in simple cases
  • Treatable by a veterinarian, by the pet parent
  • Provide regular meals and adequate nutrition
  • Transmission is not possible between animals and not possible between animals and people
  • Diagnosis requires physical exam, blood work, ultrasound

VERY COMMON IN

Kittens that are young and not eating well-balanced kitten food.

Symptoms & Signs

A kitten with hypoglycemia (low blood sugar) will lack energy. Kittens need glucose to function and perform any task. Glucose is the fuel the body burns for energy; without it the kitten is listless. Pet parents will notice that their kitten may start by being sluggish and have no interest in moving or eating and they may seem very weak. In severe instances, kittens may have seizures, since glucose is necessary for the brain tissue and muscles to function. These hypoglycemic episodes will cause kittens to fall over and appear weak or comatose.

Diagnosis

Normal kittens should have abundant energy other than when they are napping, so a change in their energy level should be alarming. Your veterinarian will begin with a physical examination of your kitten and a blood glucose blood check to determine the blood glucose level. Your veterinarian may also recommend other tests if they suspect a more serious underlying cause of hypoglycemia. This may include checking a blood chemistry for liver function and an abdominal ultrasound to evaluate the anatomy of the liver and small intestine.

Causation

Glucose is the form of sugar found within the bloodstream. Glucose is formed during the digestion of foods and it can be stored within the liver in a storage form called glycogen. Most instances of low blood sugar (hypoglycemia) in the kitten are the result of inadequate nutrition, either not enough or poor quality (indigestible) food. The severity of the hypoglycemia depends on the extent of the lack of blood sugar. If it is due to lack of food, it can be easily corrected. If the underlying cause is more serious, such as liver disease preventing the storage of glycogen, or intestinal disease preventing the proper digestion and absorption of food, then hypoglycemia may be chronic and life threatening.

Treatments

AT-HOME CARE

If you suspect your kitten is suffering from hypoglycemia, you can try to rub Karo syrup of honey on their gums while you are on your way to the vet to boost their glucose level.

SUPPORTIVE CARE

None

MEDICATIONS

Depending on the severity of the hypoglycemia, your kitten may need intravenous (IV) dextrose to return the blood glucose to a normal level.

DEVICES

None

SURGERY

None

SPECIALISTS

A general practice veterinarian can diagnose and treat hypoglycemia.

Cost Of Treatment

Most cases of kitten hypoglycemia can be treated for less than $300. In cases where there is liver or intestinal disease, costs may increase.

Recovery

If hypoglycemia is caused by inadequate nutrition or overexertion, full recovery is possible once the nutritional needs are met. Kittens with underlying liver or intestinal conditions may be at risk for additional hypoglycemic episodes.

Monitoring

Kittens should have their blood glucose levels checked every 1-2 hours until they remain stable and can eat on their own. Once this is accomplished, your veterinarian will recommend a monitoring schedule based on the suspected cause of the hypoglycemia.

Prevention

Provide meals at regular intervals and adequate nutrition.
