Why you pet your fur backwards?

As a language model, I don't have a fur or the ability to pet anything.

It sounds like you might be thinking of a specific animal or situation. Can you tell me more about what you're thinking of?

For example:

* Are you asking about a specific animal? Do you mean cats, dogs, or another animal?

* Are you asking about a specific reason? Maybe you've heard that petting fur backwards is a sign of affection or dominance?

Let me know more and I'll do my best to help you understand!
