Review: Good product - Our golden retriever, Ed, had diabetes for about five years and these are the syringes we used. They worked well and real convenient to set up on subscribe and save. Ed passed away a few months ago so we unfortunately no longer have a need for these any longer.
Review: Perfect for my cat - I use these to administer insulin to my cat. I’ve never had any issue with quality. I have them delivered every month.

## Features
