So I know that you need to feed piggies in your yard so that they don't croak (Do piggies get to squash grapes in piggie Hell?) and someone kindly informed me that piggies only need to be fed when they're unwilling to be nibbled. But how do you know your piggies are unwilling to be nibbled if you've already nibbled them as many times as you can that day? Is it a good idea to feed them once a day regardless? Or is their desire to be nibbled not reset each Glitch day?
