According to Xinzhi Encyclopedia, a blue cat with a pure white lioness will give birth to a blue lioness, a blue-and-white lioness, or a white short-haired cat. Babies born after blue cats and white cats mate may appear: mixed colors of blue cats and white cats, pure blue cats, pure white cats, cats with colors other than blue cats and white cats. If the white cat is an idyllic cat, the baby's face and skeleton will be smaller, and it won't have a face full of Sai Zhang like a pure blue cat. However, the resistance of mixed-race cats is much stronger than that of purebred cats, and the temper and personality of cats are similar.
