pregnant and panicked

When Chen Mi saw the group of groundhogs smelling the piece of cloth which belonged to his mother he was speechless, he looked at Yu Dong and then at the furry little things which were lining up in front of his wife and did not say anything for a long time. 

" What are you doing, wife?" After a very long time, Chen Mi could not help but ask as he looked at Yu Dong who was straightening up her spine after the groundhogs were done smelling the piece of cloth which held the scent of his mother. 

He thought that Yu Dong was going to use those three puppies which she brought with the children but he did not expect her to instead hand these pieces of fabric to the groundhogs, what were they going to do after smelling the scent?
