It seems like many mammals even those that would be considered exotic or dangerous seem to enjoy being petted by humans under the right circumstances. Why did so many mammals evolve to enjoy this?
In: Biology
1. The common petted location is hard to reach places, touching there is a feeling of relieve/pleasure, because its massages the underused nerve and muscle.
2. Like wise often that place is vulnerable to injury, having a trustable species that wont harm you means it establish a sort of mutual trust and appreciation.
3. Smarter ones realize social interaction is possible and naturally wanted to communicate.
4. Social and culturally is acceptable.
