If it’s true that cats have nine lives young “Oreo” has barely another to spare after a run-in with a car left her critically injured and in the care of the emergency veterinary staff at the MSPCA’s Angell Animal Medical Center in Jamaica Plain, where she is undergoing revolutionary treatment to save her life. Oreo arrived at Angell after she was hit by a car on a busy street in Lawrence, Mass. on May 20 and taken to Bulger Veterinary Hospital in North Andover. Her injuries were catastrophic: the accident left her with a mangled front left leg and with most of the skin torn away from her right hind leg, which was also fractured in multiple places. Oreo’s overwhelmed owners opted to surrender her, and the newly homeless kitty was then sent to the MSPCA-Nevins Farm, which took responsibility for her care.
