I want to live on a farm with 10 Alpacas!
Wow, I like you, well, for the fact that is a domesticated species of South American camelid.
I wonder if they like to wear sweaters?
Their hairs serve the purpose already so there is no need.They are actually  similar to llamas, and are often confused with them.
I see how they could be confused with each other. I was today years old when I found out they weren't the same animal.
Also they can successfully be  cross-breed since they are related
Wow I bet they would make great sweaters!
You bet ;) Alpacas are kept in herds that graze on the level heights of the Andes of southern Peru
What do they eat?
They eat whatever cattles eat. Alpaca fiber is used for making knitted and woven items, similar to wool maybe your sweater too :)
