A seven-month-old cat is still very young and is in a critical period of physical development. Various organs and structures of the body are not yet ready for pregnancy. Fully developed, kittens cannot be born at this time. If the pregnancy is too early, the chance of dystocia is very high. Generally, it takes until after one year of age for the cat's pelvis to be fully developed. At this time, it is suitable for pregnancy and production, and the possibility of dystocia is low.
