The user below was banned from an animal subreddit because people thought his cat was created by AI. His cat is real. I am not sure if the user used filters on his photographs but I have looked at loads of other photos of his gorgeous kitty, and the cat is just unusually beautiful!
And here are some gorgeous photos by Alexander Semenov. See them all here
Nature is amazing, the different species of animals, all unique in one way or another and the cats are wonderful. I also love the way people are able to capture those jellyfish safely, at least I take it they are still alive because the photos have survived.
