Last fall Aurora one of the Toronto zoo's two female polar bears gave birth to 3 male cubs. 2 of the 3 cubs did not survive.
keeping a close eye on Aurora and the remaining cub, staff observed the cub losing strength. The best chance for survival meant transferring the cub to the zoo's intensive care unit.
The cub veighing less than 700 grams, was moved to the Centre, a team of 27 veterinary, nutrition and wildlife care experts gave him around the clock care - monitoring his temperature, taking blood samples, weighing him and feeding him a special formula to help build up his strength.
Humphrey is now 5 months old, and doing extremely well, thanks to the dedicated team that continues to work hard to meet his physical, mental and emotional needs.
