How long does it take for Vetsulin to work on my cat?

Vetsulin typically begins to work within 1 to 2 hours after injection, with its peak effect usually occurring around 4 to 6 hours post-administration. The duration of its action can last up to 12 hours, depending on the individual cat's response and specific metabolic factors. It's essential to monitor your cat's blood glucose levels to determine how well the insulin is working and adjust the treatment as needed. Always consult your veterinarian for personalized guidance.
