It does. Individual cages; a waste chute.
1) Cages:
As if the rough construction of the ship weren't headache enough, the internal organization had to be honed to perfection. With space at a premium every cubit had to be utilized to the maximum; there was no room for oversized cages and wasted space. The various requirements of the myriads of animals had to be taken into account in the design of their quarters, especially considering the length of the voyage. The problems are legion: feeding and watering troughs need to be the correct height for easy access but not on the floor where they will get filthy; the cages for horned animals must have bars spaced properly to prevent their horns from getting stuck, while rhinos require round "bomas" for the same reason; a heavy leather body sling is "indispensable" for transporting giraffes; primates require tamper-proof locks on their doors; perches must be the correct diameter for each particular bird's foot (Hirst; Vincent). Even the flooring is important, for, if it is too hard, hooves may be injured, if too soft, they may grow too quickly and permanently damage ankles (Klos); rats will suffer decubitus (ulcers) with improper floors (Orlans), and ungulates must have a cleated surface or they will slip and fall (Fowler). These and countless other technical problems all had to be resolved before the first termite crawled aboard, but there were no wildlife management experts available for consultation. Even today the transport requirements of many species are not fully known, and it would be physically impossible to design a single carrier to meet them all. Apparently, when God first told Noah to build an ark, he supplied a complete set of blueprints and engineering details, constituting the most intricate and precise revelation ever vouchsafed to humankind.
2) Waste treatment:
All authorities on animal care insist on the cleanliness of the stalls, urging the daily removal of waste and soiled bedding. Neubuser remarks that "the removal of zoo waste presents almost insuperable difficulties" (p. 170); on the ark these must have multiplied manyfold. Creationists Balsiger and Sellier suggest that the bottom deck was used to store slurry, which accumulated to 800 tons during the voyage. However, a single adult elephant could produce 40 tons during this time (Coe), and there were many creatures even larger. Our average animal, the sheep, produces 0.34 tons per year; poultry, 0.047 (Sainsbury and Sainsbury, p. 110). Multiplying the number of vertebrates by 0.34, the seven pairs of birds by 0.047, yields 25,508 tons of waste—six times heavier than the ark itself! Of course, hibernation would greatly reduce this quantity, while the invertebrates and dinosaurs would add to it. Whatever the total, it would have been an awesome amount on the overcrowded boat, a breeder of infinite numbers of pathogens, and a source of noxious, choking fumes.
A comparison with Lamoureux's Guide to Ship Sanitation is instructive. Complex plumbing systems of pipes and pumps, air-gaps and back-flow valves, filters and chemical treatments are necessary to provide potable water and dispose of sewage. Waste is treated and dumped overboard, not discharged to the bilge as on the ark. Such technology was clearly beyond Noah's ability and the maintenance capabilities of his tiny crew; yet, if ever it was needed on a voyage, this was it.
