Here's the breakdown:
* Dogs: Have around 319 bones (depending on the breed)
* Cats: Have around 244 bones (depending on the breed)
The reason for this difference likely lies in their evolutionary history and differing needs:
* Dogs: Evolved from wolves, who were built for running and endurance. Their longer legs and larger body size require more bones to support their structure.
* Cats: Evolved for agility and flexibility, allowing them to move through tight spaces and climb trees. They have a more compact, flexible skeleton to aid in this agility.
So, while dogs and cats are both mammals with similar skeletal structures, the number of bones they have reflects their unique adaptations for different lifestyles.
