What bones do cats not have?

Cats, like all mammals, have a collarbone, but it's vestigial, meaning it's very small and doesn't connect to other bones. This is why cats are so flexible and can squeeze through tight spaces!

Here's why this is significant:

* Flexibility: The lack of a functional collarbone allows their shoulders to rotate widely, giving them incredible flexibility.

* Squeezing: It lets them squeeze through tight spaces that would be impossible for other animals.

So, while cats have a collarbone, it's so small that it doesn't play a role in their skeleton's functionality.
