While I was rearranging my cabinets one of my cats was able to get ahold of one of those plastic trays that Oreo cookies are packaged in. He started licking up the crumbs in the tray and i'm sure must have ingested some before i was able to get the tray. What constitutes a dangerous amount of chocolate for a cat? is the chocolate in an Oreo cookie even pure enough to be a risk in such a small amount?
