I remember posting probably a few years ago about a lady at work who hated cats - apparently a few times a week she gets cat cr*p on her front garden - i just hope she comes back as one in need in her next life!
I think those that don't 'know' cats find their funny ways, aloofness and unpredictability off putting. I think you have to have a cat to understand them
There aren't any animals I dislike, but I don't get the attraction with reptiles?!
