The baby yukkuri's reliance on her parent yukkuris seems to override her attraction to food! The desire to "rub rub with parent yukkuris" seems to win out over the desire for food. As to how far this kind of desire goes, we began the second part of the experiment.Finally, the sobbing became wailing screams! The baby yukkuri completely lost interest in eating and dove over to the model's side, "rub rubbing" with the model as she cried out "YUUAAAAAAAAAAAH."Yu... Wuuuuuuuu.... Wuuuuu.... Yuyu.... Wuuuuuuuu.... Wuuuuuuuuuun...During the eating process, the baby yukkuri showed abnormal behavior. She didn't make a "munch munch" sound, and didn't say "Happineeeess!" Rather, she seemed to be unwilling, closing her eyes and wrinkling her forehead and forcing down the food. Finally, the baby yukkuri didn't seem to be able to bear it and started crying while eating!We put an electrical wire into the model. The electrical current is enough to cause suffering to yukkuris, but not enough to kill. We would like to observe if the baby yukkuri would still demonstrate an attachment to the parent yukkuri under these circumstances.YUUAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAH!
