No, not human brothers but polar bears!  The Highland Wildlife Park at Kingussie is celebrating  the first 'happy anniversary' of two polar bear brothers.  Arktos (5 years old) and Walker(4) have become inseperable since they were first brought together. The playful pair who are the UK's only polar bears on display, happily play, wrestle and swim together in their pond. Their close bond has been a welcome relief to staff at the park who were initially concerned that they would not get on together.. A member of staff at the park said recently that he had found the bears one evening 'sound asleep side by side, with their feet resting on the other bear, both confident in each other's company'.
