Quick, easy, convenient, they work and manage with my vet

Delivery on time. Only issue was the insulin, which has to be refrigerated, was in a "cooler" box but the two ice packs were completely thawed and the carbboard box that the insulin was in was wet and falling apart.

So far this was the cheapest option for purchasing the insulin my vet had prescribed for my cat

Newman's vet started him on this when he was first diagnosed with diabetes. He's done well on it and has had no side effects from the usage of Pro-Zinc.

I purchased ProZinc from Petco because I received a huge savings over what I was paying through my vet. With 7 cats any savings is appreciated.

My cat is 14yrs old and was Dx'd Diabetic in fall of 2018. He's been on Vetsulin since then and only needed 1 unit 2x a day, some days we were able to skip a dose. We decided to try ProZinc because of the high remission rate associated with it, but sadly, it hasn't helped my cat at all. He's on 2 units 2x a day and his numbers are still in the 250-300 range. Nothing else has changed, so I don't believe this type of insulin is compatible with him. Back to the Vetsulin we go sadly. At least we got to try it out.

i have a diabetic cat. this is his required medication

Cat has been on a couple of insulins since being diagnosed & ProZinc seems like he is most stable & comfortable. Other insulins had to change dosages frequently.
