That would be my dream pet! If I find ayone I shall let you know! Do alpacs count?
I've been doing a bit of reading and apparently there is quite a bit of difference in temperament between llamas and alpacas.
Llamas are gentle whereas alpacas can be asocial, and will come to you on their own terms. Also both are herd animals and it's generally not recommended to own only one as this can lead to several problems.
The ickiest of these is that a llama/alpaca which is poorly socialised away from others of its kind will see humans as llamas and will spit at you. That doesn't sound very nice...
But if you have the time and space for a few of them they make great pets and are generally clean and disease free.
Also their poop makes great fertiliser
