As has already been said, I personally do not think that those categories are necessary. If this was a larger wiki, it might make sense to have categories for each species, like raccoon or bear; but mammals, amphibians, reptiles, birds, fish, insects and any others would be too broad to be helpful, and yet too empty (for all of those except mammals) to have a point. Those type of categories are either side of the sweet spot for a necessary category.

To further illustrate my point, I'll create an example that does not focus on animals. Say you had a wiki with an article about Black Forest Cake (Sly Cooper). It is very clearly a Food (Character). But it's more than just a Food, it's a Dessert (Mammal). Even more than that, it is a Cake (Raccoon). On your wiki, you have a few Cakes, which are Desserts, but the majority of your articles are not Foods at all, but are actually Books. Do you create categories like "Desserts" or "Cakes" to fit your few articles of Food into, creating many extra categories (such as Sandwiches) for only one or two articles? You could, creating dozens of mostly empty categories, but the category of "Food" will suffice.
