And when veterinarians noticed the particular way he shuffled along the floor, they aptly named him Elvis, after the hip-swinging rock-and-roll legend.
"He was pretty feisty when he first arrived at the hospital, which was a good indicator that he'd be a suitable candidate for short-term care and release," Taronga's senior veterinarian, Larry Vogelnest, said in a statement.
And indeed he was. Just days later, Elvis was bouncing around the hospital. Rescuers realized that it would soon be time to bid him farewell.
