Naples Zoo is in the midst of its Lions, Tigers and Bears 09 summer extravaganza.  The lions include two South African lion cubs that now reside at Naples Zoo and that will eventurally participate in the Association for Zoos and Aquariums Species Survival Plan.  For their big first birthday celebration this past Sunday they were treated to special lion-friendly ice cakes, frozen with milk and beef blood.  Zoo guests watched the cubs tear into their ice cakes during the Meet the Keeper presentation at their exhibit in Lagoon Loop.  I happened to go by the zoo last week and spent some time watching these two.  They are brother and sister and can reside together for several years until they reach breeding age.  The boy is just starting to get his mane and the girl is showing signs of growing into a beauty to rival that of Nala's.  You can still see their spots, which will fade as they continue to mature.  They're still playful and have a cute fuzzy appearance.  Over at Black Bear Hammock, the smaller female bear was quite inqisitive, checking out the railroad crossing and all of us looking at her through a pane of glass.  A beautiful white tiger with blue eyes is currently on display in the bamboo jungle tiger exhibit.  The zoo's Malaysian tigers are taking a break from exhibit life but will return soon.  Be sure to visit www.napleszoo.org for coupons and information on show times before your next visit.
