Their Mom’s Not There
There was confusion among the firefighters as to why the mother wasn’t with the children. In the first place, it was totally illogical for the babies to be there. If they were in the wild, it would have made some sense, but that wasn’t the case.
Are They Abandoned?
The firemen first had to figure out the sewer’s layout before carrying on with the rescue. It is possible that the mother and father of the animals were there, but the firefighters’ arrival frightened them. They still have to figure out what kind of creatures they have been rescuing.
