The first five out? Let's see here....
Okay, my reasonings for this order are: In the first group we have four kittens and an adult to look after them. In the second group we have the rest of the kittens and two adult queens. In the third group we have four queens and a tom for protection in case he's needed. In the fourth group we have the elderly and Jellylorum stayed behind to join that group to look after him. Then more toms. The last group includes more of the "leaders" of the tribe.....kinda along the lines of the captain is the last one off the ship. Well, that's my take on it anyways.
