“I use this product as a preventative when I purchase a new parakeet, but I use it half strength since parakeets are small birds. It seems that no matter what store I purchase a new parakeet from, they end up with tail bobbing which is a sign of a respiratory infection. This product has always cured that problem. I only use it for the first two weeks, and then my parakeets live from four to twenty-two years after that without needing it again. It does cure the tail bobbing issue.”
