Here's why:
* Evolutionary Differences: Domestic cats evolved from wild cats, but pumas are a completely separate species with different vocalization systems.
* Purring Mechanism: Purring is a unique physiological adaptation found in most domestic cats. It's thought to be a way for them to communicate, self-soothe, and even heal. Pumas don't have the same vocal cords or muscle structure that allows for purring.
So, while pumas may be related to domestic cats, they don't share the same purring ability.
