The polar bear mother Vilma and her daughter Anori, born 03.01.2012, are clearly enjoying the pool and the enrichment that is provided. They both were very active -- in the pool -- during the day of my visit on 27 July, 2013. And let's be honest, what is the best place on a hot summer's day? Indeed, a nice cold tub.And you can hear the Californian sea-lions, which have their enclosure adjacent to the polar bear's, agree to this statement.
