Got a ragdoll X cat, beautiful girl she is, but she has a wierd problem..

She wont let me pat her at all with my hands, if I put my hands anywhere
near her she runs off, but if I try and scratch her with my feet, she
LOVES it ! will let me do anything to her with my feet

Sometimes if im very slow she will let me use my hands for a bit, but she
soon runs off..

Anyone know what could be going on here ? id love to be able to pat her
properly now and then

Any advice would be great.
Thanks.
