Why doesn't a cat carry its kittens? - briefly
Cats do not carry their kittens because they rely on their young to stay in a secure nest while the mother hunts or moves them only when absolutely necessary.
Why doesn't a cat carry its kittens? - in detail
Cats, unlike some other mammals, do not typically carry their kittens in their mouths or on their bodies for extended periods. This behavior is rooted in their evolutionary biology and the specific needs of their young. Newborn kittens are altricial, meaning they are born in a highly undeveloped state, blind, deaf, and entirely dependent on their mother for survival. Their delicate bodies are not suited to being carried, as it could risk injury or displacement from the nest. Instead, mother cats focus on creating a safe, warm, and hidden environment for their litter, often choosing secluded spots like closets, boxes, or dens.
The mother cat’s primary role is to nurse, groom, and protect her kittens during their early weeks. Carrying them would disrupt this process, as it could expose them to predators, environmental hazards, or unnecessary stress. Additionally, kittens are not equipped with the physical adaptations, such as strong limbs or gripping abilities, that would allow them to cling to their mother during movement. In contrast, species like primates or marsupials have evolved specific anatomical features to facilitate carrying their young.
However, there are exceptions to this behavior. If a mother cat perceives a threat to her litter, she may move her kittens one by one to a safer location. This is done cautiously, as she gently grasps the kitten by the scruff of its neck, a natural reflex that causes the kitten to remain still and compliant. This method ensures minimal risk to the kitten while allowing the mother to relocate them efficiently. Overall, the absence of regular carrying behavior in cats is a testament to their instinctive prioritization of safety, stability, and the developmental needs of their offspring.
