Pet Yukkuris are said to be of the highest grade, and are normally trained/conditioned to be obedient and less selfish than wild ones, often by trained personnel and adult yukkuris directly in the shop. Furthermore, due to the high number of "defective" and "livestock" yukkuri among the regular ones, Pet Shops may sell "new" accessories to owners who want to "fix" a yukkuri with a damaged accessory. The accessory are often harvested in the same shop. Another "secondary" product sold in Pet Shops are additional Stalks, for consumption uses, taken from livestock yukkuris.
