Little Cub, lacking the aid of forelimbs, inadvertently slipped after taking two bites. Wanting to eat again, it struggled for a long time but couldn't reach, crying out in distress.
The mother cat glanced at her child, turned slightly to expose her soft belly, then reached over to grab the cub by the back of its neck, lifting it onto her stomach so it could lay there and feed.
Yunyun was somewhat stunned; she originally intended to help by supporting the cub's body from underneath, not expecting the cat mother to make such a sacrifice.
After all, the belly is the softest area and the part they most need to protect. Normally, even while feeding their young, they would at most turn sideways, exposing their bellies around other animals, are you crazy!
