The charity is holding its “Big Knit for Vet Kit” fundraising campaign and is asking knitters to make Duncan the donkey, Hattie the horse or crochet Clarence the camel and get sponsored while they stitch. Joining the other animals, a brand new pattern – Oscar the ox – is being launched in 2015 and is available to order.

The campaign is supported by model, designer and actress Twiggy Lawson. Twiggy, who is an animal welfare campaigner and keen knitter, said: “I know everyone will have so much fun knitting their very own gorgeous camels, horses, oxen and donkeys, with the money raised helping SPANA treat a real working animal in one of their clinics in Africa or the Middle East.

“It's a privilege to be supporting this campaign as SPANA continues to work tirelessly in some of the world's poorest countries, ensuring working animals are well looked after and given the care they deserve.”

The funds raised from sponsorship and donations will help SPANA provide more free veterinary treatment to working animals in developing countries across the world.
