I scratch my cats chin all the time. What are you on about? (Edit: I be wrong. There’s no chin there)

  Jaw vs chin, I’m guessing the difference is fairly small.

    Looked at wiki. The chin apparently is just the part of bone that juts out under the lower lip. So yeah, no chin on the cat.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)

Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.

** Posts must be about an actual fact that you have learned, but it doesn’t matter if you learned it today. See Rule 6 for all exceptions.**

Rule 2- Your post subject cannot be illegal or NSFW material.

Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.

Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.

Rule 4- No self promotion or upvote-farming of any kind.

That’s it.

Rule 5- No baiting or sealioning or promoting an agenda.

Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.

Rule 6- Regarding non-TIL posts.

Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.

Rule 7- You can't harass or disturb other members.

If you vocally harass or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.

For further explanation, clarification and feedback about this rule, you may follow this link.

Rule 8- All comments should try to stay relevant to their parent content.

Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.
