Actually, Namin? will say that there needs to be better plans for what to do with custom pet starvation... A few other custom pets have to go through extremely annoying hunts just to get a low drop custom food. Garm Baby is probably the most affected by this... Ninetails is almost the same.
Possible to add custom pet's food to taming gift set, or a new "bag item" that opens up random pet food perhaps? Hunting ninetails just to get 3-4 tofu in an hour sucks
