It’s headed that way, but rather slowly. Even the space requirement is sort of experimental stage. Some people think certain animals need more space, especially the members of the public, what people forget is quality versus quantity of the space. The large mammals may not necessarily require in terms of the simple figure, but what quality do you give them, as opposed to quantity. Flat space, or a variety of climbing devices. Up and down levels. There is an open field. A lot can be done.
