Are you sure it wasn't an email from when the line came out in Canada? I've seen formula changes regarding their foods, only to realize it was the changes from last year, lol. As far as I know, AAFCO has NOT changed their labeling of Milk Thistle, meaning this food will NOT be in stores in the US. Plus, if we were getting them, I'm pretty sure our rep would have mentioned it, since he is in our store a lot and was basically beating down the door to get Ranchlands on our shelves.
