Yes, white cats are considered rare.
Based on available information, white cats are some of the rarest, constituting only about 5% of the total cat population. This relatively low percentage makes their striking snow-white coats quite unusual and dazzling. While all cats are special to their families, their distinctive appearance contributes to the perception of white cats being particularly unique.
This rareness, quantified by the 5% figure, means that encountering a pure white cat is significantly less common than seeing cats with other coat colors or patterns like black, tabby, or calico.
