“They must be related to Camels because they spit and have that look about them.”
Precisely. They most definitely are related to camels. They are one of four surviving camelids in the Western Hemisphere. There were other species during the Pleistocene but they died out.
And yes, llamas make good pack animals (if you don’t mind the spitting). It is one of their major jobs back home in South America. They are are lighter than horses or donkeys and do less damage to the trails.
They can also be jogging or hiking companions (although quite frankly, I prefer a dog).
Llamas can be used to pull carts, if you have any carts that need pulling, and you can learn to drive the cart.
They can be used to make more llamas, which is their primary use in the United States and Canada.
Depending on the individual animal’s temperament, llamas make good pets.
Llamas are often used as therapy animals.
It has been reported that some adventurous owners use their llamas as golf caddies.
There are “show llamas” so there is also a market for llama stud service.
Some people like to watch llamas so in a way they are decorative.
As others have said, you can use them to guard sheep, goats, cattle or even chickens because they can kick the fool out of any predator that comes around.
Female llamas (would that be “Mama llamas”?) do produce drinkable milk, but not in huge quantities. Llama milk is lower in fat and salt and higher in phosphorous and calcium than cow or goat milk but they make only a small amount at a time.
Yes, llamas are good for sweaters, but their wool is coarser than that of the alpaca, so it actually is better for rugs and storage bags.
And yes, you can eat llamas as they do back home in Peru and Ecuador, but Americans tend to look on them as cute, fuzzy animals, like dogs, so the market for llama meat is not so big here.
