And Chilchuk is a Gambian pouched rat, because they can be trained to sniff out land mines, and safely, since they're too light to trigger them. He's on fours because otherwise he wouldn't be able to keep pace with everyone.

Oh, yeah, and Izutsumi is a girl cat. (I initially didn't plan to have her here, but since she'll be appearing soon, I decided to add her. The thing is, I'm not sure she would resist pouncing on Chilchuk, so it might be better to let her nap while they walk.)
