This is my answer to “what if Fluffies groomed themselves like cats/dogs/regular horses?”
My guys would definitely be like cats, licking front hooves and wiping themselves, biting itchy spots, “nomming” each other’s manes, doing the “loaf”, but also hitting that pentagram pose with one rear leg up xD I would say that XXLs (like Marcelline below) would probably be more built and dexterous to self-groom completely, while standard Fluffies would be already too plump to reach their rear.
Me and my brother call it “the 4th dimension itch” - there is no other way to scratch it, and even worse when it happens around the chin or the nose x"D
