If there is some 'errata' published for this, I would like to have Carnivore Feed applied to size "Tiny". I have a ferret, and it would make sense a "day's" supply would be worth 2 to 4 days for him, or perhaps 2 for Tiny, 4 for Fine, 8 for Diminutive, or something to make it clear. I am going to presume each 'days' supply covers him for 2 days, and I do not expect a GM to argue the point. But having a handy reference would be dandy. :)
