Alex didn’t mind watching the goats. It was clearly the stupidest and lowest-status job in Troupe life, but at least there was very little to it. All the goats had smart collars, and you could set the herd’s parameters on a laptop to give them minor shocks and buzzes when they wandered out of range. They were gene-spliced pharmaceutical goats, "pharm animals," and despite their yellow, devillike, reptilian eyeballs, the goats were remarkably docile and stupid. Most of the time the goats seemed to grasp the nature of the collar business, and they stayed where the machine wanted them. They industriously nibbled anything remotely edible and then lay in the shade belching gas from their gene-spliced guts.
