Monarto Zoo's five cheetah cubs celebrated their first birthday yesterday along with the zoo's youngest southern white rhinoceros, Kibibi, who also turned one. Curiosity eventually got the better of the inquisitive cubs, who made their way down to their "gifts" - a papier-mache zebra and antelope filled with fresh meat. While rhino Kibibi enjoyed her enrichment gift of a present filled with her favourite food - hay. Monarto Zoo's cheetah cubs celebrate their first birthday with a cardboard zebra full of meat. Picture: Luke Hemer GALLERY: Monarto Zoo's babies Monarto Zoo curator Beth Pohl said both species had adapted to life at the zoo well. "It's fantastic to see Kibibi develop her own personality and presence ... she's definitely living up to her royal name sake, princess," she said. Monarto Zoo's South White Rhinoceros, Uhura and Kibibi, celebrate Kibibi's first birthday with a hay- filled cake. When Kibibi was born she weighed 40kg but now the one-year-old tips the scales at 530kg. Cheetah cubs - Jana, Hizi, Kulinda, Kesho and Mikele - are doing well too. The siblings are often seen pouncing and playing with each other in their enclosure. "They are the first and biggest cheetah litter to live at Monarto Zoo in more than nine years and have captured the hearts of staff and visitors alike," Ms Pohl said.
