I've always really enjoyed the llamas I've met and was wondering about them. How expensive are they to keep? What about feed, do they require grain, what about hay quality? Are their feet like goats, and need to be trimmed? Are they prone to certain diseases? How often do you have to shear them? How trainable are they? I think that's it... I'm not going to just go out and buy one today, but I do like the idea of having one in the future...I think. Thanks for any info!!
