Sneaking Trail is really just another way to raid, just within each Pack. Here you can steal females from other packs within Kahli's Pack. The same rules for raiding and capturing apply here, only captives switch packs instead of sides. You cannot steal a Dark Canine or a Light canine here, only within Kahli's Pack.

When stealing, post this in the subject: "I, (your name), steal (captive's name) from (lead canines's name of captive's pack)." Then post in the captive's pack, politely, that they have been captured and must come to your territory. The highest available canine in the captive's pack may then post here that they would like to reclaim the captive. I'll tell you if the canine remains captured or not by rolling a die.
