    "Bought for a rooster"

    My rooster had bumblefoot, and I had to do some digging. And thanks to the compression of a chicken shoe I bought for him, one toe turned black and was dead and had to be cut off. Veterinarians have a huge markup on antibiotics, and I refuse to play. Thank goodness this manufacturer offers us an alternative to greed.

    "Fish Mox is great!"

    My fish couldn't sleep because of mucus and sinus infection. After about four days of Fish Mox they sleep great. I didn't even need to go to the Fish Doctor.

    "Good value"

    I used these before for their intended use as well antibiotic use for pets. It's the same drug as the vet would use and gives good results for common bacterial infections
