When a character who doesn't normally have animal-like features (such as ears or a tail) is drawn with animal ears or a tail.
This can also include characters who are canonically animal-like, but are depicted with a different set of animal features (for example, a dog girl being drawn as a cat girl). Note, however, that this does not include characters who can become animal-like, such as Inu Sakuya or the Strike Witches.
When there are more animal-like features like a snout or full fur, use furrification instead.
