I strongly suggest that Kemonomimi should be used instead of animal_ears.
Not only is it confusing to people who do not know what animal_ears means (animal-like ears?) it also leads to more trouble when attempting to use the equivalent of *mimi (nekomimi, okamimimi, etc) in the animal_ears format (cat_ears, wolf_ears, etc) which would lead to even greater misuse.
Furthermore, most furries are more familiar with the term kemonomimi than animal_ears.

Please fix this problem.
