My two rats are 5 months exactly today and there rats poop is small and grey, They haven't had there normal food because we ran out and can't go to nelson for a few days.

Iv'e fed them a boiled egg, And some carrots and apple slices,
And they are very hydrated and get fresh water at all times,
So I don't know what to do! Can you please tell me what to feed them or what to do?
