I don't know why, but it's a sad fact that "cat-haters" tend to be far more vehement in their opinions. I guess it's why cats, and people who like cats, have had such a bad press historically in this country.
Typically the scenario was : "Elderly" lady + cats = Witch/crone/nut job.
They forget how useful cats have been to society, helping to keep down vermin - ships cats came about because of rats on ships spreading the Bubonic Plague.
