Diabetes in Cats

Monitoring Urine
Glucose & Ketones

Tracking Diabetes in Your Cat’s Urine

Immediately following diagnosis, your veterinarian may ask you to check your cat’s urine to monitor glucose and ketones. Depending on your pet, this may be done 1–3 times a day:

  • Early in the morning, just before the Vetsulin® injection
  • Late in the afternoon, just before the second injection
  • Late in the evening

If monitoring once daily, the measurement should occur at the same time every day.

Collecting Urine

As treatment progresses, less frequent testing will be needed. Regular examinations remain important though, because your cat’s Vetsulin needs can change

Tools for Collecting

  • Clean containers for collecting urine
  • Urine dipsticks from your veterinarian
  • A place to record results

How to Collect

  • Have a clean, dry container (dish, bowl, or small pan) ready to catch urine when your cat urinates
  • Place your cat in his litter box
  • When your cat begins to urinate, slowly slide the container under the urine stream
  • Alternatively, there are special cat litters that can help with urine collection, such as hydrophobic (non-absorbing) sand. Kit4Cat is one brand that can be top coated to your regular litter.

VETSULIN® and VETPEN® are for use in animals only. Dogs and cats known to have an allergy to pork or pork products should not be treated with VETSULIN®. VETSULIN® is contraindicated during periods of hypoglycemia. Animals with severe ketoacidosis, anorexia, lethargy, and/or vomiting should be stabilized with short-acting insulin and appropriate supportive therapy before use. As with all insulin products, careful patient monitoring for hypoglycemia and hyperglycemia is essential. Overdosage can result in profound hypoglycemia and death. Progestogen and glucocorticoid use should be avoided. The safety and effectiveness of VETSULIN® in puppies, kittens, breeding, pregnant, and lactating dogs and cats has not been evaluated. Keep out of reach of children. Avoid contact with eyes. In case of contact, immediately flush eyes with copious amounts of water for at least 15 minutes. Accidental injection may cause clinical hypoglycemia. In case of accidental injection, seek medical attention immediately. Exposure to the product may induce a local or systemic allergic reaction in sensitized individuals. For complete safety information, refer to the product label.
