The very first cat I adopted(way back in 1988), was a WHITE TORTIE. Miss BooBoo Kitty quickly taught me what tortitude was all about!!! For 16 yrs, she was my BEST friend. Now, Hayley, a black tortie, is at our house. She is my husband's best friend, and I am despised!!! Then to round things out, there is Nimet, a lovely calico. We once participated in a study about cats and their colours. It was NO suprise to find out that the ORANGE cat is the MOST sensitive....
