A cat was found locked in the basement of Redding Town Hall yesterday.  The medium-sized short-hair orange tabby scratched and bit an employee, drawing blood.  Redding officials say this could be a potential health threat for that person and are calling on residents to help identify the cat's owner to provide proof of rabies vaccination.  The cat's right ear was clipped. He was skittish with men but ran to females. The cat rubbed on people’s legs but when touched, hissed and backed up.  Anyone with information is asked to contact Redding Animal Control at 203-938-3400 with any information.
