As the title says, once I open a tray of Nature Diet, how long until I have to throw it out? It is kept in an airtight tub a cm or so bigger than the tray its self and opened 3 times a day if that makes any difference. It's just, it takes me AGES to get through a whole tray! She gets half the marked section here (I was reducing the ND and increasing the JWB a bit). Oh, and thats per meal not day :lol: Should I maybe, divide it up and freeze? I don't want it going off or anything.
