Tiggy is now around 2 years old - she turned up a year ago and within a couple of weeks was displaying "kitten behaviour". This included the fighty bitey bit (only my hands - everyone else said she didn't bite!) She still had her kitten teeth (little needles) at the time and like any baby there is a teething process - they chew! When Tiggy got too much with the biting etc I gently held her scruff and made a disgruntled me-ow sound which stopped her in her tracks. I guess I was "Mummy". This stopped and it only happens (gently) now when she's playing. Tig has loads of toys which she does play with from balls, small catnip toys to a circuit with a flashing ball. Today, however she preferred to chase a fly that had the mis-fortune to find its way into the house - bad move for the fly - great fun for Tiggy x
