Introduction
If your cat has been diagnosed with diabetes, you may be wondering what the best insulin for them is. While there are a variety of options out there, it’s important to work with your veterinarian to find the right one for your cat’s needs. Here, we’ll provide an overview of some of the most popular types of insulin for diabetic cats so that you can make an informed decision.

The Different Types of Insulin
There are a few different types of insulin available for diabetic cats, and your veterinarian will help you choose the best one for your cat based on their individual needs. The most common types of insulin used to treat diabetes in cats are:
Regular insulin: This is a short-acting insulin that is typically given twice daily. It begins working within 30 minutes and peaks in 2-4 hours.
NPH insulin: This is a longer-acting insulin that is typically given once or twice daily. It begins working in 4-12 hours and peaks in 12-18 hours.
Lente insulin: This is a longer-acting insulin that is typically given once daily. It begins working in 6-14 hours and peaks in 18-24 hours.
Ultralente insulin: This is the longest-acting insulin available, and it is typically given once daily. It can take up to 24 hours to begin working and can peak anywhere from 24 to 36 hours after injection.
How to Choose the Right Insulin for Your Cat
If your cat has been diagnosed with diabetes, you may be wondering which insulin is best for them. While there is no one-size-fits-all answer to this question, there are a few things to consider when making a decision. Here are a few tips on how to choose the right insulin for your diabetic cat.
1. Talk to your veterinarian. They will be able to give you specific recommendations based on your cat’s individual needs.
2. Consider the type of diabetes your cat has. There are two main types of diabetes in cats, Type 1 and Type 2. Type 1 diabetes is typically managed with insulin injections, while Type 2 diabetes can often be controlled with diet and exercise alone. Your vet will be able to advise you on the best course of treatment for your cat’s particular type of diabetes.
3. Consider the severity of your cat’s diabetes. If your cat’s diabetes is mild, they may only need insulin injections once or twice a day. However, if their diabetes is more severe, they may need multiple daily injections or even continuous glucose monitoring and insulin therapy (CGM/IT). Again, your vet will be able to advise you on the best course of treatment for your cat
The Pros and Cons of Insulin

Type 3 insulin is a newer type that falls somewhere in between Type 1 and Type 2. Its effects last longer than Type 1 insulin, but not as long as Type 2.
Each type of insulin has its own advantages and disadvantages, so talk to your vet about which one would be best for your cat’s individual needs.
