The list definitely needs to be reorganized. When I make a post with a fox in it I immediate look under Mammal...but it's not there. There's a Vulpine section but the only listings are "Fennec" and "Vulpine (Other)". It feels like at times the list is too specific and at other times it's too vague. Personally, I think the super specific species or breed set up is too much. Simpler terms like "Bear" covering all bears, "Fox" covering all foxes, "Dog" covering all dogs might be simpler with specified breeds or sub types being something the user tags specifically themselves.
