Just wondered if anyone else has this problem using this food? I bought a 10kg bag off zooplus as I wanted something of reasonable quality and grain free but affordable. They enjoy it and eat it just fine, but wow! They stink! Not only their poops are gassing my flat out, but they're farting constantly and have a permenant pongy smell whafting around their back ends now, even though their bottoms are clean. Anyone else had this issue using grain-free foods? Oddly enough, they didn't smell half as bad on the cheaper stuff.
