    It’s a BIG bottle!

    By Bridey51 on Feb 23, 2021

    My Vet recommended I order my cats B12 from Chewy. I had been purchasing at the clinic as needed. This bottle is huge, but at a fraction of the cost of my usual small vial. The outdate is far enough out but even then I won’t go through the bottle. Buying another when the time comes will still be cheaper than 1 vial at clinic

    Energy booster: Appetite Booster: Check with your veterinarian

    By Troublesniffer on Dec 25, 2020

    When this is appropriate, a subQ Vitamin B-12 injection may be able to boost the energy and appetite for cats, especially for cats with chronic illness. Our veterinarian introduced us to injectable Vitamin B-12 many years ago and it was extremely helpful for our kitty with Chronic Kidney Disease. Since this is an Rx item, it needs a prescription from your veterinarian.

    Easy to administer

    By CatsCauseTypos on Jan 11, 2021

    Our vet recommended we start subcutaneous vitamin B injections for our elderly cats, and this does the trick! Easy to withdraw precise amounts many times over with the high quality rubber stopper.

    Thanks Chewy!

    By Chica on Jan 19, 2021

    This is a prescription item. Despite Chewy having to contact my vet for approval to sell this to me I still got very quick delivery of the B12 that my geriatric cat and dog need. Than

    Chewy is the best!

    By Nick on Jul 27, 2020

    Chewy is the best online pet food/pharmacy. My vet recommended Chewy. This medication requires a prescription and Chewy makes it so easy by contacting your vet and keeping you informed. I have ordered many cases of food through the years and Chewy has never made a mistake with any one order. Chewy is the best!

    good product, not so great service

    By Buford on Aug 29, 2020

    This product is great, would recommend this brand to others. Great price for the volume. Took OVER a week to get here - which is why I only gave this 3 stars.

    Great Product for B12-Deficient Kitty and Great Price

    By Lauren on Jun 11, 2020

    This product has been great (as prescribed by my cat's vet) to help my B12-deficient boy. He gets it as prescribed by the vet due to a few health issues he has, and his energy and demeanor improve within a couple days after an injection of it. The price here is also so much better than any injection price at the vet—by a lot. I would definitely get the B12 through Chewy and learn to do the injections at home—IF you’re comfortable with it.

    Older cat and dog, both with health issues. Has given them more energy.

    By piper on Jun 26, 2020

    Our vet and the vets at the hospital recommend the shots. Easy to give, even with the kitty. Easier than pills.

    I am glad Chewy has pet medications!

    By Star on Apr 3, 2020

    The Vet recommened my dog receive a weekly shot of B-12. In one year I do not use up a bottle of B-12. I was disapointed the expiration date on the B-12 I received is Oct. of 2021, just a year & half from now April 2020.
