    Cheaper than a vet.

    By on

    Was prescribed eye drops for my guinea pig who had her eye removed. Was told I would probably need these drops for her for the rest of her life. Went on Chewy just to compare prices, and it was HALF the price of my vet. I get a 10% discount from my vet because I have multiple animals. But even with the discount it is still HALF the price. My vet gave the consent to Chewy. I am a very happy customer.

    Happy with product but not with Chewy!

    By on

    This product has been extremely helpful with the eye condition in our westie. It is helping immensely to bring his eye back to normal, along with warm compresses. I am not happy with the fact that the vet instructions on the label were incorrect and I was essentially blown off by them and told to look elsewhere for correct information, which delayed me from using the product. I also was greatly delayed in getting the product delivered as Chewy dragged their feet on getting a script from my vet here locally. Totally unnecessary.

    Very good product

    By on

    Very good product, although it arrived very late, requiring a number of correspondence and calls. For that, we should blame the Corona thing, of course

    Great Rx... Really Helped

    By on

    When other Rx’s didn’t work for our cat’s eyes, this really helped with his chronic eye problems! Better than the teramyicin or the prednisone drops!
