I just read a lot of bad reviews from this 2014 Feb. I bought them them before but didn't notice anything. I'll give just a few to make sure tho. Mine likes any kinds of treats, I do use crappy Friskies..but I also get good stuff too. She loves catnip but not the fresh stuff I bought yesterday so will dry it and see. Maybe it was sprayed or grown in bad stuff? Seems healthy tho.No, but that's a lot of negative anecdotal reporting. Since I'm not enamored with the ingredients and don't see how they really help with dental issues, I don't ever plan to feed any Greenies to Aria even though I got a free sample as well from my local pet store.
