He was immobile and seemed to be in pain. He was also dangerously thin and covered in fleas. Indeed, it was remarkable he was still alive.
When the opossum arrived at a rescue center, Wildlife Haven Waterloo (WHW), Joy Huggins, the founder, was shocked at how determined to survive this little opossum was, given his condition. Underweight, weak, dehydrated and already missing his right paw (it looked as if he'd sustained a previous injury and had to have his leg amputated), there was something very wrong with his left paw.
Rescuers named him Saber, to lend him the strength of a saber-toothed tiger (and because of his prominent teeth).
At the vet, X-rays revealed that, while there were no fractures, something had caused the bones of his paw and leg to separate and that's why Saber was having such a hard time moving around.
