Pete was on Little one and ate (or horded) most of it then because I had difficulty getting more I bought Science Selective to mix with the remainder of the Little One he ate the Science Selective and left the Little One of which I managed eventually to get another bag it's been in the freezer 3 weeks now I'm not sure what's the best thing to do keep buying both or stop buying the Science Selective and hope he goes back onto the Little One that I still have a full bag of in the freezer just wondering what you would do ?
