Harder to read on a small dose. Might not be as hard on a large dog, but on a cat, it is not accurate enough.
I have a diabetic cat, and these work great. Most important is the smaller 0.3cc capacity. Trying to give 1-3 unit doses using giant syringes is a pain and can be dangerously inaccurate. Smaller syringes with 30 gauge, short 5/16" needles are more humane, accurate and safer.
Beacuse I need 2 a day I was looking for a good quality sharp at a great price. I had been using a different brand but swapping to these made sense and now I will buy these regularly.
