I have one co-worker who spend a night in the house of a friend of hers. That friend had to go to work earlier and so Chris was alone with the cat: up to today she says the cat didn't allow her to leave the house by standing in the door and looking threatening.
So she is not really mad crazy about cats but mildly scared.
I have to take it as it is- but I still would think the irrationally-scared-by-spiders fraction is bigger than the irrationally-scared-by-cats fraction.

Filou just said he loves the idea that someone is scared of him- he is rather bothered by all the people who want to kiss him
