Here's a great guide to Caninsulin (lente):

However, there are several reasons why I would recommend asking your vet to switch to Lantus (glargine) or Levemir (detemir) instead of sticking with Caninsulin. (Prozinc is difficult to get the UK.)
1. Caninsulin works well in dogs, but it doesn't work well for cats because their metabolisms are about twice as fast as dogs or humans so each shot only lasts about 4-8 hours. Even if you are shooting twice a day, the Caninsulin is not working to lower blood glucose levels the entire time. Lantus and Levemir are long acting insulins that last 24 hrs in dogs or humans, so each injection will last a full 12 hours in cats.
2. Lantus and Levemir are much safer to give than Caninsulin. Hypoglycemia (dangerously low blood sugar) happens more frequently with Caninsulin than the longer acting insulins because it causes very sharp drops in cats. Also, because it doesn't offer very good control of blood sugar, most vets tend to overdose it in an effort to bring blood sugar down. Too much insulin will keep blood sugar just as high as too little insulin, which is why it's very important to hometest daily so you have a true picture of how the insulin is working in your cat. Hypoglycemia can be deadly in an instant--even if a cat has been on the same high dose for some time with high blood sugar.
It's also very important that when you change the diet to low carb canned food, you must drop the dose down significantly regardless of insulin type because it can cause a deadly hypoglycemic incident. We usually recommend dropping down to 1u.
3. Lantus and Levemir have a proven 84% remission rate for cats that start treatment within 6 months of diagnosis, together with home testing and a low carb, canned diet. The sooner you switch insulins, the better are your chances of remission (remission is when a diabetic cat no longer needs insulin, and blood sugar levels can be controlled by diet alone). Caninsulin has less than a 25% chance of remission, and most cats that reach remission on it would have gone into remission regardless of insulin type because they were changed to a low carb, canned diet.
I've attached a couple articles for you to print out and show your vet to help you convince them to give you a script for one of these insulins. If your vet refuses to change insulins despite the research, I would try and find a vet that will accept the research and work with you.
