Just don't put two or more in the same trap / container for transport or you will see one hell of a fight / bloody mess. My dad was catching some once and hauling them to a local park. Decided to save a trip and held one in a box overnight, then caught another, and dumped both in the same container for transport. Freaked my mom out. they fought to the death, or at least one of them did! I did not see it but heard the story several times, not a pretty sight. They obviously were not friends.
