yukkuri food
Factory produced feed for pet yukkuris often in the form of small pellets, similar to dog food or cat food.
Like dog/cat food, it's contents and taste varies between each brand and flavor and there are higher and lower quality yukkuri food. But in general it seems to taste better than food foraged by wild yukkuris (grass, insects, flowers, etc) but inferior to sweet sweets. Higher quality ones can even induce spoiled tastebuds against lower quality food.
In some stories these yukkuri food are actually made from slaughtered yukkuris just like most other factory products.
