We use these needles to test our diabetic cat's blood glucose levels. They're very sharp and easy to handle.
I have a cat who is in the early stages of Renal Failure. I have to administer subcutaneous fluids twice a week and give him B12 shots once a week. I originally purchased this product thinking it was the same type of syringe I use for the B12 shots. However when I received them, I figured out it was just the needle portion. I was mad at myself because I ordered the wrong item. However, I started thinking about the fact that I could detach the needle from the syringe and attach one of these needles to the syringe. Then I could use the syringe over and over for the B12 shots but just switch out the needles every time I give my cat a shot. This works perfectly and does not waste plastic by having to use a syringe only one time.
