Newborn kittens are born blind, deaf, and completely helpless. Yet within minutes, they crawl toward their mother and begin nursing. Since their eyes and ears open only after one to two weeks, kittens must rely on other senses.
Like many mammalian neonates, they depend heavily on smell and touch to locate their mother’s nipples (Larson & Stein, 1984). Queens (mother cats) produce chemical cues from their mammary glands, and kittens instinctively respond to these signals.
Olfactory Cues (Smell)
Smell plays the most critical role in the early orientation of kittens. The mammary region of the queen secretes odors and pheromones that act as attractants. Even on the first day of life, a kitten will turn and crawl toward a lactating female but not toward a non-lactating cat (Blass & Teicher, 1980).
Just a few days after birth, kittens can already recognize the unique scent of their own mother’s teats. This built-in sense of smell acts like a natural compass, helping them head straight to the right place instead of wandering aimlessly. Researchers have even found that when a kitten’s sense of smell is blocked, it can’t find its mother to nurse—a discovery first highlighted in studies by Larson and Stein back in 1984.
Tactile Cues (Touch)
A kitten’s little face, muzzle, and whiskers are full of super-sensitive nerves. When they bump into mom’s fur around the belly, it kicks in what’s called the rooting reflex. The kitten starts burrowing, wiggling its head, and then opens its mouth to grab onto a nipple (Veterinary Key, 2023).
Researchers found that if kittens can’t really feel things—like when their sense of touch is blocked—they struggle to find the nipple, even though their nose still points them in the right direction (Larson & Stein, 1984). So basically, touch works hand-in-hand with smell for that final step of nursing.
Thermal and Social Cues
Warmth also influences neonatal orientation. Kittens are strongly attracted to body heat, both from their mother and their littermates. This thermotaxis helps them maintain body temperature and indirectly brings them into contact with the nursing area (McNair, UC Davis, 2022). Social huddling ensures survival, reinforcing the likelihood of successful feeding.
Reflexes: Rooting and Suckling
Newborn kittens are equipped with reflexes designed for survival.
- Rooting reflex: Touching the cheek or muzzle makes the kitten turn toward the stimulus. The kitten pushes its nose and forelegs against the mother’s ventrum until it encounters a teat (Veterinary Key, 2023).
- Suckling reflex: Once the nipple touches oral tissues, rhythmic sucking and swallowing begin automatically. This reflex is strongest in the early days and weakens after weaning (Blass & Teicher, 1980).
Even blindfolded kittens and puppies display these reflexes, confirming their innate and hardwired nature.
Neural Mechanisms of Suckling
Suckling behavior is not learned but driven by brainstem circuits known as central pattern generators. These neural networks produce rhythmic suck–swallow actions without conscious control (Blass & Teicher, 1980). Thus, newborn kittens can coordinate jaw, tongue, and swallowing movements from the very first feeding. Higher brain areas refine efficiency later, but the foundational circuitry is present at birth.
Learning Process and Maternal Recognition
Although orientation begins as instinct, kittens quickly learn to recognize their mother’s unique cues. Within the first few days:
- They begin to favor specific nipples.
- They discriminate their mother’s odor from that of another lactating female (Larson & Stein, 1984).
This olfactory memory strengthens the innate search process. Even after separation, kittens can reunite with their mother using learned scent profiles.
Conclusion
The ability of newborn kittens to find milk is a finely tuned survival mechanism. Despite being blind and deaf at birth, kittens successfully nurse within minutes thanks to:
- Olfactory guidance from maternal odors,
- Tactile cues from whiskers and fur contact,
- Reflexes such as rooting and suckling, and
- Rapid learning of maternal scent.
These instinctive and learned mechanisms reflect strong evolutionary pressure, since any delay in nursing reduces survival chances. Together, they ensure that kittens can feed immediately and thrive.
