Hedgehogs come to the centre when they reach a weight over 900 grams. The Zoological Centre explains on their Facebook page that the amount of overweight hedgehogs is steadily increasing, the centre is now seeing the same overweight hedgehogs coming back time after time.
People leaving bowls of pet food outside. Every day is Christmas when those cute little hedgehogs find a plate of cat food, and they just can't help but gorge themselves, plus they don't even have to take more than a few steps.
"Hedgehogs who used to find their food through a long walk and search, using up energy, can suddenly gather around a near houses, public gardens and enjoy Our Cornucopia."
Sherman the hedgehog (pictured above) is the poster boy for the new slimming program from the Ramat Gan Safari Zoo.
Dr Yigal Horowitz, veterinarian and director of the wildlife hospital, explains that while a fat hedgehog may sound adorable, the creatures struggle to survive in the wild.
"When he came to us to the wildlife hospital, we realized immediately that he had no medical condition except for obesity, which is disease as much as any other disease."
Sherman was to be put on a diet before he could be released back into the wild.
Sherman how came in weighing over 1kg has already lost two grams and the center are hopeful this is only the begging.
