There is a probability that blue cats will produce blue and white children when mated with British shorthair cats with white hair. For example, if mated with blue and white cats or with pure white cats, the probability of producing blue and white children is relatively high. If two blue cats are mated, the probability of giving birth to blue and white is very low, unless one blue cat has a recessive gene for blue and white.

Blue cats will go into estrus when they are 6 to 12 months old. Generally, female cats become sexually mature at about four to five months, and some later ones need about one and a half years old. The sexual maturity of male cats is relatively late. It is usually recommended to breed around eight months, but it can also be postponed according to the actual situation. When breeding, you should pay attention to the fact that purebred cats should choose the same purebred, so that the offspring will be more pure. It is best not to mate with cats with large size differences, otherwise dystocia will easily occur. It should be noted that Russian Blue cats cannot be bred with British Shorthair blue and white cats or British Shorthair white cats because the breeds are different.
