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.

Myoung Ho Lee‘s 2007 Tree series is about as peaceful and serene as the scenery itself. In the series, the young South Korean photographer touches upon the subjects of physical isolation and visual confirmation. By placing the tree in front of a stark white background, Lee creates a false separation that plays a delightful game with the mind’s eye.

In the 1970′s, actress and model Tippi Hedren (mother of actress Melanie Griffith) created the Shambala Preserve after producing the film Roar. The preserve rescued exotic big cats living in captivity that had been abused or were in need of help, one of which the family created a close bond with. Neil the lion lived with the family in their home, and played an active role in the day to day activities of the preserve.
