I ran out of pellets for my guineas and theyre 4-5months old and im having some kms pellets/hay come in in 2 days so i really dont want to go out and buy a whole bag of pellets when there will be a whole other bag of them here 2 days from now, it seems like a waste of money. Would it be okay for me to give them a little bowl of critical care each day until the pellets come or will an unlimited supply of hay and good source of vitamins through veggies be fine?
