Not sure if this is your photo, but what this cat is doing could be a sign of a serious medical problem. If this is your cat, I would get this floofer to the vet ASAP.
Not sure why you are being downvoted - if anyone has a cat that does this, this is not typical cat behavior, it generally does mean something may be wrong with your cat. Yes. Some cats do it just because - but often times it does mean they are unwell and youl should get them to a vet.
I think some people just want to look at cute photos of cats without thinking about negative things. I can understand that. But if I posted a photo of my cat exhibiting what could be a symptom of a serious problem that I wasn't aware of, I would want someone to tell me. I know OP said this is a repost, but I still think it's important for anyone who loves their cats to be able to tell if something is wrong. This doesn't look like normal cat behavior to me.
