Why are humans pregnant for longer than cats?

Humans are pregnant for longer than cats primarily due to differences in fetal development and brain size. Human infants are born with larger brains that require more time to develop in the womb, allowing for the complexity needed for higher cognitive functions. In contrast, cats have shorter gestation periods, as their offspring are born more mature and able to fend for themselves relatively quickly. This evolutionary adaptation reflects differing survival strategies and developmental needs of the species.
