Scottish Fold Cat

    Kittens showing heat does not mean they are ready to breed. This first heat is called the initial estrus period, during which the reproductive organs are not yet fully developed. After some time following the initial estrus, the male and female cats' reproductive organs are basically mature. Males’ testicles can normally produce sperm, females’ ovaries can release mature eggs and show estrus cycles. If allowed to mate, they can conceive and give birth, indicating they have reached sexual maturity.

　　However, cats just reaching sexual maturity have not yet reached physical maturity, meaning their bones, muscles, and certain organs are not fully developed. Breeding and pregnancy too early can affect growth and development, resulting in smaller size, premature aging, shorter lifespan, poorly developed offspring, smaller body size, low survival rates, increased illness, and breed degradation. Therefore, cats must reach basic physical maturity before breeding. Normally, female cats reach sexual and physical maturity earlier than males. By general experience, breeding is more appropriate at 12 months of age for short-haired cats and 18 months for long-haired breeds. For some cats, breeding time should be even later.
