Tomi and Gjina are also happier and healthier.
"Tomi is just really quiet and he loves to lay down all the time, and he enjoys everything - the sun and the snow," Hoti said. "Sometimes he's quite active, and he likes to climb the wooden structures that we have in his enclosure."
"Gjina is really quiet - she doesn't do that much stuff," Hoti said. "Lately she is going in the pool, and she's trying to find out the way to communicate with the other bears next to her enclosure."
Gjina is the youngest of the three bears and, for Hoti, her transformation has been the most remarkable.
