I am becoming quite an active member in GPAC, or Greyhound Pets of Atlantic Canada. I am forever reading and posting on their chat board, and someone mentioned feeding their grey Iams. Well, let me tell you I'll never buy it. I did not know the history of Iams, but they do all their testing for their products on animals. There was a big undercover report that was done showing exactly how these animals were treated. I was physically sick to my stomach watching this. If you dare, the website is http://www.iamscruelty.com/, but honestly, I warn you, it's gruesome.
