Update--I've been switching their food and they are stinking less, thank goodness! I had a bag of Canidae that I got on vacation, they did wonderfully on it, no more diarrhea, no more puking--but then I couldn't find it around here so I bought Nutro Natural Choice Weight Control instead (b/c they're all roly-poly). They are doing well on it so far but it's only been a couple days. We'll see! It's got to be better than those corn chips that pass for Purina cat food!! :lol:
