How do the shape and structure of the uterus of the cat compare with that of the human?

The uterus of a cat is more elongated and has a larger horn structure compared to the human uterus, which is more pear-shaped and single-chambered. Cats possess a bicornuate uterus, meaning it has two distinct horns that can accommodate multiple embryos, reflecting their reproductive strategy as induced ovulators. In contrast, humans have a simplex uterus, designed for carrying a single fetus. Overall, these structural differences align with the reproductive needs and behaviors of each species.
