Normally llamas only spit at other llamas. However, they have lousy aim and it's easy to get caught in the crossfire. Usually its just saliva but when one gets really PO'd, they'll hack up green stomach contents. It's harmless but smells terrible. Once in a while, they'll spit at a person but they have to be pretty mad. I have 1 gelding that really hates having his feet trimmed. To do it, I strap him to a heavy gate so he can't lie down, then snub his nose up tight so he can't get a bead on me. He'll scream and spit but it all hits the wall and I come out fairly clean. When I'm done, I remove the straps and give him just a little slack on the halter and let him stand there 5 or 10 min to calm down before I let him go.
