  • Mr White Cat - RIP

    Mr White Cat - RIP

    Mr White Cat was something of a celebrity at Hillside Veterinary Clinic! He claimed Hillside Veterinary Clinic as his new home after being found in a drain. He basically ran the practice and could usually be found lounging on the reception counter, ignoring us simple humans. Mr White Cat was deaf, but that did not stop him from living life to the fullest! We will never forget this handsome chap!
