Alpacas are a smaller cousin to the llama and they are sheared of
their fabulous fiber once a year.
They need less room than other live-stocks for several reasons,
(A)
They process what they eat more thoroughly so that they need
less feed, (B) When they graze, they do not pull the grass
roots up
killing the plant, (C) Instead of hooves which also kills grass, they
actually walk on a pad and have
two toe nails.
They do spit at each other but rarely at humans. They have to be
really frightened to spit at
a two legger. The females take eleven
months to have a baby and for alpacas and llamas they are called
'cria'.
Sheep produce a LOT of lanolin which collects in the wool making
it smell more than alpacas and because alpacas produce
so little lanolin,
it makes washing their fiber in preparation to spin it a breeze.
