Alpacas and llamas enjoyed a late festive feast after owners treated them to recycled Christmas trees. Mary Harvey, who runs CHAT - Chy Lowen Alpacas Tregaswith, Cornwall - revealed the camelids 'love' to munch on Christmas trees in an appeal on social media. She was inundated with trees. One tree lasts about a week, however, they now have enough to last the pack a whopping three months. Video shows one of her animals, Dusk, happily eating a Christmas tree. Mary said alpacas and llamas like to graze on hedgerows, but there isn’t much available in winter, so Christmas trees provide a tasty and long-lasting alternative. Christmas trees - which are usually pine, spruce or fir - are a source of vitamin C and antioxidants, making them great dietary supplements for both alpacas and llamas. CHAT is a non-profit organisation that is dedicated to helping children and young adults with a variety of issues using animal-assisted intervention (AAI).
