UltiCare VetRx 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.

We have purchased this item 15 times. This last purchase, April 27, 2025, was different. The size of the white cap is slightly larger. But honestly, no one cares about the size of the cap. What I'm reviewing today is a change in the product itself. Now, the puller is very loose. It does not pull an even amount of the cat's insulin. I have to push the insulin back in the bottle and pull again, multiple times, to get it right. But then something else worrisome happens...the puller, on it's own, slides to push the insulin out of the syringe. I tried multiple syringes from different bags in the box. They all have the same problem. As if life is not difficult enough as it is, here is a product that we relied on and purchased 15 times, and now I have to find and try a different brand. If something has worked forever, why do companies make a "new and improved version" that is significantly worse than what they were making. For the first 14 purchases, I would give this 5 stars. For the last box, 0 stars. Thus the 1 star review - as a warning to fellow purchasers that they have changed the product and not for the better.Edited on 5/14/24: This seller has outstanding customer service. They saw our review and right away emailed us. They have not only refunded our purchase, but they are sending a replacement and investigating the lot. Sometimes mistakes happen in production, this happens, but to have a company reach out and make things right is outstanding customer service. We are changing our review to 5 stars. We will stay a loyal customer to this company.

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.
