These syringes are great, very easy to use, nice clear markings for small doses of insulin and VetUK has the cheapest price I found online. But they are costly so if you're looking for an alternative, look at the VetUK syringes because they have one that is exactly the same as this, just the markings are slightly different. When my cat was first diagnosed I was very confused about the whole syringe thing, there's a lot of numbers to get the hang of and I worried I would get the dose wrong if the markings on the syringe were different. The VetUK syringes don't have 1, 2, 3 markings, they have 5, 10, 15 instead but there are little lines for 1/4 doses so you can work out where to pull the insulin too. Yes, it's slightly harder to work out but the savings make it worth it for sure! Give them a try if you're looking for something like these syringes.
