A newborn kitten finds its mother without seeing her face or hearing her call. Smell and touch do the work. The wide-eyed orange-and-white kitten resting on an open book has already passed that first, precarious stage, when survival depends on senses that operate before sight and hearing are ready.
Those sealed eyes are not a design flaw. Kittens are born neurologically immature, and development continues after birth; closed eyelids help shield the developing eyes during that vulnerable period. Their ear canals are closed, too, and the auditory system is not yet ready to process sound as it will later. The lids and canals gradually open as the kittens mature, though an open eye does not immediately mean adult vision. Development takes time. The precise evolutionary reasons for this early dependence are not fully settled, but it is consistent with a broader pattern among mammals whose young are born relatively helpless.
The route to milk is less mysterious than it looks. Olfaction, or the sense of smell, helps a kitten orient toward its mother, while touch and warmth guide its small crawling movements against her body. Once there, rooting and suckling reflexes help it latch and feed; its mother also draws her litter close and keeps it warm. None of this requires a conscious map. On the open page, the kitten's gaze seems to promise independence, but its first journey was made in darkness, guided by a scent and the warmth of another body.
