Perfect size

Unfortunately we were not able to start using the insulin as my precious baby wasn't able to use it when we received it But we had used the same exact type prior

Unfortunately we were not able to start using the insulin as my precious baby wasn't able to use it when we received it But we had used the same exact type prior and if you are in need of insulin for your fur baby and they aren't using a lot of units, this size is perfect.

wish you could use the whole cartridge.

Ok to use with the pen once you get used to it, but there's at least a whole shot that remains in the cartridge. But my human friend says the same thing happens

It doesn't get any better than at Chewy! As our fur baby got diabetes we were thrown into the deep end of trying to figure it out. We had many questions regarding insulin, needles, etc. but Chewy came to the rescue. The pharmacists and pharmacy tech's were amazing. I called them at all hours and they were so informative and patient. They even called my vet for me. Chewy goes above and beyond in their knowledge and customer service. I would recommend them in a heartbeat.
