You can build a pen with a ramp to lure these guys in. I suggest using doorframes rather than windows because it's movement pattern can make for a lot of missed shots. Make sure yoy have a TON of narcotics on you as the torpor of this creature drops fast. For a 135 it required 225 narcotics. Starve tame just in case anything wanders into the pen and makes you lose efficiency. If this happens, let it wake up and then knock it out again. It's food will still be relatively the same so you won't have to wait the 1hr plus for the starve timer. Great tame, but expensive.
