Buck

This is Buck, a scout for the savages

He and his siblings  Moose and Doe are a team dubbed The Deer. The three of them work  together very well, almost like reading each other's minds. 

Buck is the  sort of leader of the group. He's the brains and generally comes up with  the plans. He's also very good with other cats so he tends to do all  the talking, too.

The three of them were sort of barn cats  before they joined the savages. In that they lived in a barn on a farm.  But they weren't cared for by twolegs and in fact the twolegs hated  having them around. Their parents were either killed, captured, or  chased off by the twolegs, I haven't decided. But yeah, sneaking around  the twolegs is part of where they learned to be so sneaky.

Buck led his siblings to join the teeth, although they tend to stay back, a little away from the group, watching carefully. When necessary, Buck will give Tooth then impression that he hangs on his every word and admires him as a leader. Tooth laps this up, pleased he has such an elite team of scouts amongst his followers.
