Dressing against the cold is hard when you're a 6,000-pound elephant. But thanks to some generous knitters (编织者) in Mathura, India, a group of elephants have giant handmade sweaters to help them stay warm during the cold winter. When worn with their bright red leg coverings, their new outfits look like comfortable nightclothes for them!

The huge sweaters were made for elephants at the Wildlife SOS Elephant Conservation and Care Center. It takes care of 20 blind, lame, or injured elephants. They were saved from abuse (虐待). Some lived in circuses, some were bought and sold illegally, and some were not receiving enough care. In India, elephants are sometimes kept in crowded inner cities and used in street performances or for begging. This causes physical and emotional harm to the wild animals. Wildlife SOS provides food, care, and medical attention to those animals.

Because most of the elephants housed at the center are recovering from injuries or are elderly, “it is important to keep our elephants protected from the bitter cold during this extreme winter,” explains Kartick Satyanarayan, the co-founder and CEO of Wildlife SOS. “They are weak and vulnerable (脆弱的), having suffered so much abuse, making it easy for them to catch diseases such as pneumonia (lung infection). The cold also worsens their arthritis (关节炎), which is a common issue that our saved elephants have to deal with.”

At first, Wildlife SOS made giant jackets out of tarp (防水帆布) for the elephants to wear. Then they asked people in nearby villages to help out by making colorful knitted sweaters. Knitting the sweaters is a big undertaking. Each one takes about four weeks to create, with volunteers working together on the very large sweaters. Wildlife SOS hopes to save 50 more elephants this year — which means there could be a lot more knitting to do!
