When I was about 3 my cat, Rocky, died. He was about up to my waist when he died and untill about second grade I beleived that he was up to my waist, even as I grew, and I soon thought that he was the only house cat as big as a tiger. I believed this until my friend pointed out that he was up to a 3-year-old's waist, not a full grown person's waist.
