This adorable and unlikely pair of best friends are inseperable. Kitty the kitten was abandoned and Buttons the Jack Russell was rejected by his mum. They eat, sleep and play together while they are being hand reared at our centre in Old Windsor, Berkshire. We would love for them to find a new home together when they are ready to leave our care in the near future.

Paddington the Shar Pei dog and his best friend cat named Butler are perhaps the cutest pair you've ever seen. The two of them live with their owner Annie Jacob and three other cats in Tasmania on the south coast of Australia and are pretty much inseparable.

Opposites can attract and Anzac a doe-eyed baby kangaroo has become best friends with Peggy, a tiny squint-eyed wombat. Their unlikely union developed after the pair - both orphans - shared a pouch at the Wildlife Kilmore Rescue Centre in Victoria, Australia. At just over five months old, Anzac was brought to the centre after being rescued in the Macedon Ranges. The joey is in the mother kangaroo's pouch for about eight months, depending on the species, but Anzac was abandoned a few months before he was ready to be free.

A merino lamb attempts to jump out of its enclosure to find its mother shortly before feeding time at the Educational and Reserach Station for Animal Breeding (Lehr- und Versuchsanstalt fuer Tierzucht und Tierhaltung, or LVAT) in Brandenburg state on January 27, 2012 in Gross Kreutz, Germany. Hundreds of lambs have been born at the LVAT in recent weeks in the midst of the station's lambing season. Many of the lambs will be sold just before Easter, when they will have grown to a weight of over 40kg, as lamb is the traditional German Easter meal. (Photo by Sean Gallup/Getty Images)
