    I've been using these syringes for awhile and just simply prefer them over any brands I've tried. Highly recommend these!

    .3cc Syringes

    Posted by Linda Kincheloe on Oct 11th 2025

    These little syringes are perfect for my Timmy's insulin. The shorter needles are easier to insert under the skin without having to worry about them sticking out through the other side. Plus, you can't beat buy two boxes, get one free.

    Easy to see small doses

    Posted by Sarah M. on Oct 7th 2025

    Great for patients on very small doses of Vetsulin- so far clients that have switched over have been much happier. They also said their cat's seem more comfortable receiving the injection.

    Great product

    Posted by Heather Henriksen on Sep 27th 2025

    When our cat was diagnosed with diabetes we felt bad every time we had to inject him. I read about a finer needle that wasn’t so painful & the only place I can find them is through Pet Advocate. We’ve been using them for a year and are very satisfied.

    Good syringes , great prices

    Posted by Timothy Hill on Aug 30th 2025

    I actually prefer these over the more expensive U40s because the needle is smaller length and thinner yet still feels the same when injecting so I'd like to think it's less painful for the cat. The markings include half unit markings and all are clear and easy to read.

    Pet Test Syringes

    Posted by Elly on Jun 21st 2025

    I love my diabetic cat and I want him to be comfortable when I give him his insulin shots twice daily. I buy what l consider to be the best syringes. I chose the 31 gauge and l believe he doesn’t even feel his shot . I’ve been using these for over 2 years and he never shies away from me at shot time. I highly recommend these syringes to anyone who may have a pet that relies on shots to maintain their health..

    Posted by Marty on May 6th 2025

    My little 12 pound girl doesn’t even flinch when I use these needles. They have been a game changer for us.

    Good syringes

    Posted by Timothy Hill on Feb 23rd 2025

    Sharp, good flow for insulin during usage and length of the needle itself seems just to be just-right, not needing to penetrate deeper than needed so I would like to hope it's a less-painful ordeal for my cat.

    I like this small size. My dog doesn’t feel a thing when I give her an injection.
