Handling a Diabetes Emergency

Understanding ahead of time what to do if an emergency occurs can help save your cat. This includes talking to your veterinarian for more information tailored to your cat’s care.

Reasons for Low Blood Sugar (Hypoglycemia)

The most common side effect experienced with Vetsulin^® (porcine insulin zinc suspension) therapy, or other insulin preparations, is low blood sugar, called hypoglycemia. If not treated, hypoglycemia can be fatal to your cat.

By knowing the causes of hypoglycemia, you can help avoid occurrences. Hypoglycemia can be caused by:

• Giving too much insulin
• Missing or delaying food
• Change in diet or amount fed
• Infection or illness
• Decreased appetite or vomiting
• Change in the body’s need for insulin
• Adrenal, pituitary, or thyroid gland diseases, or progression of liver or kidney disease
• Interaction with other medications
• Increase in activity
• Remission of diabetes

A cat with diabetes may experience hypoglycemia without showing any obvious signs. It is important that pet owners be particularly observant of their cat’s behavior.

If Low Blood Sugar Occurs

These side effects can happen suddenly, and require immediate care:

• Weakness
• Depression
• Behavioral changes
• Muscle twitching
• Anxiety
• Seizures
• Coma

If your cat is conscious:

• Administer the treatment recommended by your veterinarian. If unknown, rub a small amount of corn syrup on your cat’s gums. (Pouring it risks it getting in the lungs.)
• Corn syrup is absorbed very quickly (1–2 minutes), and your cat should be responsive
• After your cat can swallow, feed a small amount of food
• Contact your veterinarian immediately for further instructions
• Your pet may need to be hospitalized for treatment

If your cat is unconscious:

Contact your veterinarian immediately, this is a medical emergency! If your veterinarian is unavailable contact your local emergency clinic.

Keeping Blood Sugar Stable

Managing care with consistency helps prevent low blood sugar emergencies.

• Keep diet consistent and appropriate
• Feed at the same times each day
• Treats and changes should be avoided unless recommended by your veterinarian
• Your veterinarian will advise on diet based on your cat’s response to insulin treatment
• Exercise and level of play should not change without consulting your veterinarian
• Develop a schedule with your veterinarian for regular evaluations

Other Side Effects

Be aware of signs associated with loss of effectiveness of insulin, or allergic reactions. Contact your veterinarian immediately if your pet shows signs of the following:

• Excessive water consumption for more than 3 days
• Excess urination, including urination that is abnormal for your pet (nighttime for example) or inappropriate (like urinating in the house)
• Reduced or complete loss of appetite
• Weakness or seizures
• Behavioral change or depression
• Muscle twitching or anxiety
• Constipation, vomiting or diarrhea
• Signs of a bladder infection (small, frequent urinations, straining, blood in the urine)
• Swelling of the head, neck, or insulin injection sites
• Ketones in the urine
• Change in gait, involving walking on the hocks (ankles)

If you feel your cat is at risk for developing diabetes, consider having your pet tested during a regular veterinary examination at least once a year.
