Probably a capybara, or a cheetah. Both are rather chill animals, and cheetahs are fairly able to be domesticated (and have been multiple times throughout history) at least compared to other big cats.

Both are still a really bad idea, and the latter will probably result in injury or death. After having interacted with two Cheetahs through a rehab centre, I’d be open to try.

At this point there are so many of them, its literally just spam. Also, a lot of the time it’s very NSFW stuff that doesn’t get flagged at all.
