Is it a difficult job to raise a llama?
Well, it's not a walk in the park, that's for sure.  But it's worth all the trouble.  They are my babies!
I've never raised a llama but I got my Siberian Husky when he was just 4 weeks old.
Huskies can be a handful, too, but they are no match for a llama.  Llamas spit...all the time.
How do you get used to that? That would gross me out.
I wear a protective see through plastic mask.  Llamas can grow up to 6 feet tall and weigh 450 pounds!
Wow. I can't believe that a llama can weigh that much. What do they typically eat?
They graze on grass like cows.  They make great guard animals for other livestock.  
So you can raise them on a farm if you want to?
Absolutely, and their hair can be used to make warm clothing.
