What happens if you don't shear an alpaca?

Alpacas do not shed their fur like a dog or cat. They must be sheared annually for their own health and welfare. Not shearing them is what is cruel because they can't manage the summer heat. An alpaca who is not sheared regularly becomes matted and unmanageable.
