With dogs and cats, it is easy to observe them all day and night, and as they tend to trust you and let their gaurd down, you get to see all sorts of cute dreaming behavior.
This is more difficult with alpaca. They are never all asleep, as some remain on gaurd duty. Those that are awake will react to your presence, and the sleepers usually awaken in response to this activity.
I just had a fun opportunity with A1. She is completely deaf, and was fast asleep. I kneeled down next to her, and watcher her dream. He little lips were twitching, and her facial muscles were quite active. And she was humming. As she is deaf, I know this was not due to external stimuli.
I wonder what alpaca dream about?
