Fletcher has been on 100% raw for years because of his IBD, but in an attempt to save some money and time, I have been feeding the girls half raw/half kibble for a few years. Never had any problems until recently, when I opened a new bag and Sallie immediately got the runs. I didn't connect it with the food right away, because Molly was fine, but after a couple of days the penny dropped, and I took Sallie off the kibble and she improved immediately. I know big companies "tweak" their formulas all the time, depending on available resources, maybe your company changed something as well? It doesn't necessarily mean they are a bad company, but I am sure they would want to know about what happened. I would take the girls off kibble if Molly didn't like hers so much I may still do it, haven't decided.
