UltiCareVetRx U-100 Pet Insulin Syringes, Comfortable & Accurate Dosing of Insulin for Pets, Compatible w/Any U-100 Strength Insulin, Size: 3/10cc, 31G x 5/16’’, w/Half Unit Markings, 60 ct Box

My dog has diabetes and these needles are easier to administer the vetsuline , but you have to be careful with the conversions egen using a different type of needle to this one. You can give your dog too much insiline or too little. Make sure you speak to the vet or your dr. if you switch needles. These are stronger at the needle tip making it easier to administer the insuline.

Got these for my cat’s insulin. I like the half measurements and can give a better dose with them. I also like the size of the syringe and needle. I do wish the writing other than numbers and markers was lower so it isn’t near the first 5 units and therefore would be even easier and clearer to see. I have started to prep the AM shot when I do the PM one so it is already set and ready to go in the early hours when I need to give the first shot. I have excellent vision and the marks with the writing and black stopper were causing me to take longer so early in the morning so this helps me be confident I’ve got the dose right. They work well. Recommend if you need syringes like these.

Do you have a diabetic pet that requires U-100 insulin doses involving half unit increments? Do you have poor eyesight and the thought of trusting your eyes to accurately and consistently estimate half unit increments make you queasy? THEN THESE U-100 INSULIN NEEDLES ARE FOR YOU!My eyes aren’t horrible but they’re not great either, particularly in the morning. I had an extremely difficult time finding needles with half unit markings. These are more expensive than some other needles, but they allow me to accurately and consistently measure my sweat boy’s U-100 insulin dose. Good and sharp for painless, no fuss, injections.I have a Maine Coon, male, very thin … he was not overweight when he developed diabetes, and he became underweight and lost most of his muscle mass during diagnosis/finding correct dosage. Good length needle for his coat and lack of fat/muscle. If needle was too long we had occasional through-and-though injections; if too short it wouldn’t get through his coat reliably.

Works perfect for my small dog, seems to be painless.

High quality product from a reliable seller. The extra half-unit marks enable higher precision.

4 out of 5 stars.I previously used the human insulin syringes only because that was what the vet had prescribed when my cat became a diabetic. The human needles are longer than these pet syringes. Although I can use my FSA account to buy the human insulin syringe, I decided to stick with these needles because I have gone through his skin and poked myself in the finger a couple times due to the needle length. I can’t use my FSA for these which are a bummer, but I find that these are much more user friendly for our pets so I am sticking to these. Measuring lines were good for the first 2-3 boxes, but this last one I got…the lines were way off. Luckily for me, I use a caliper to measure his dose so it is consistent every time no matter what the lines on the plunger does from one syringe to another. If you don’t already use a digital caliper, you need to get one. Join the FB group Feline Diabetes Support Group. They can help you with the calipers and feline diabetes in general.

Easy to use. Clear markings.

I have to use the U-100 syringes for my cat who has diabetes. I've purchased three different boxes of syringes from this company. Two boxes were the U-100 kind. One of those boxes was of the U-40 kind, which was a mistake on my part, but one I ended up being glad I made because the needles, at least, were longer on those. I just had to figure out the dosage for my cat using those syringes in lieu of the U-100 ones.Anyway, I've had so many problems with this company's syringes because the needles often bend on me! This tends to happen when putting the needle through the top of the insulin bottle. BUT, the worst time was when the needle bent while trying to inject the insulin into my cat! That resulted in my poor kitty getting stinky fur with insulin on it. She had to lick that off when grooming herself, too! Yuck!But worse than that, it resulted in my not knowing if any of the insulin actually made it into her before the needle bent, or if I needed to re-administer the complete dosage! That's a potentially life threatening problem! I had around 1/8 of the needles bend on me from each of the first two boxes. The most recent one, though, has been even worse than that! I've had at least 1 in 5 needles bend on me! This results in a lot of wasted money and potential dosage problems when they bend like that!The reason I have gotten these syringes despite the problems is because the vet ended up doubling the price of the syringes they were selling! However, I can't keep purchasing syringes with weak needles like this. I'm now stuck having to find a different brand with stronger needles.One more thing: cats have thicker skin than dogs. They need longer needles like the ones in the U-40 syringes. I do not understand why the ones on the U-100 from this company are so short! It could be part of the problem with the needles bending!
