The "Crazy Cat Lady" stereotype didn't come from nowhere. There are many obese ladies out there with quite a few obese cats. Obese because none of them eat right and get no exercise. I know one lady who thinks it's OK to share her icecream with the cats as long as it's vanilla. Wtf.
Of course, happens with dog people too. But I hear of it more with cat people who have more than 10cats.
