Had to go for some hay today for my stallion and the alpacas were being shorn when I got there. Very interesting to see how it is done, and how intelligent those animals are. They are rolled sideways onto a table, then have their neck strapped down and then their legs stretched out so they can't kick, or move and hurt themselves or anybody helping. Some accepted it and just lay there quietly, while the occassional one would scream, and such a high pitched sound you'd swear it would shatter wine glasses.
One of the women would simply pat it on the neck and talk quietly to it and it'd stop that and lie quietly. I was told their intelligence is on par with a pig or dog.
