Molly has had JWB ocean fish for the past few months with no 'runny' probs. I do add a sardine, cheese or white fish with it. Have they all got a bit of a tummy bug I wonder?
No, I'm sure they haven't I think it's an intolerance to something in it. I've changed them to a different flavour, mixed with Nutro as well, and they're fine, thank goodness.
Mine have been on that for a year or two now and no problems. My boy occasionally goes a little loose, but it's more likely the other treats he gets! :-)
