My cat Pishi (RB ) never liked my husband. She never accepted him, always giving him 'the look', never letting him touch her.

My cat Eddy doesn't like other females. She only likes me, that's it. She hits my mom, she hisses at female friends - but she loves all men!

I always think, that cats see an aura or something, and it might be that your friend has an aura that doesn't suit her. This sounds very esotheric, but otherwise I can't explain it.
