Cats were domesticated thousands of years ago. Are they finally getting tamer?

Cats, which have been domesticated for thousands of years, are showing signs of growing closer to humans in ways that suggest their domestication might still be evolving. Social media platforms now host millions of cat profiles, with cats frequently accompanying their owners in public spaces, and surveys indicate that most pet owners view their cats as family members. This shift raises questions about whether cats are becoming more tame, or if it is human behavior that has changed. The idea that domestication could continue even after initial contact with humans is supported by research on other species. Biologist Kevin Parsons and his team at the University of Glasgow studied red foxes in London and the surrounding countryside. They discovered that urban foxes exhibit physical traits typically associated with domestication, including shorter, broader snouts and smaller braincases. These changes are linked to reduced fear of humans and greater adaptability to urban environments, where food and shelter are more readily available through human activity. Similar patterns are emerging among fallow deer in Dublin’s Phoenix Park. Ecologists Laura Griffin, Simone Ciuti, and colleagues observed that some deer regularly approached humans for food, while others remained distant. Among the more bold individuals, female deer gave birth to heavier fawns, indicating that willingness to interact with humans may confer reproductive advantages. These findings suggest that proximity to humans can influence behavioral and even genetic traits over time. The question arises: Do these observations apply to cats, which have been domesticated for millennia? While cats are often considered less domesticated than dogs, due to their independent nature and lack of selective breeding for specific tasks, they have shown remarkable adaptability. Unlike dogs, which were bred to perform roles such as herding or guarding, cats largely domesticated themselves by choosing to live near humans, drawn by the abundance of prey in agricultural settlements. Cats' success in adapting to human environments stems from their behavioral flexibility. In areas with limited resources, they tend to live solitary lives, defending their territories. However, in regions where food is abundant, such as near human dwellings, they can coexist peacefully, forming stable social groups. Some researchers propose that cats initially developed tolerance for one another before extending that tolerance to humans, highlighting a gradual evolution in their ability to interact with people. Early experiences with humans play a crucial role in shaping a cat's personality. Kittens exposed to frequent positive interactions during their critical developmental stage, typically between two and seven weeks of age, are more likely to become confident, affectionate adults. This indicates that cats possess inherent potential for forming bonds with humans under the right conditions. Rather than undergoing fundamental biological transformation, they may simply be revealing capacities they have always had. Human lifestyles have also undergone substantial changes in recent decades, influencing the dynamics of the human-cat relationship. Fertility rates have declined globally, with women giving birth to approximately two children instead of nearly five. As people delay parenthood, live alone for longer periods, and rely more heavily on companionship, pets like cats have taken on new roles in fulfilling emotional and social needs once met by extended family structures. These shifting societal norms have altered not only family compositions but also the expectations placed upon pets. As human needs evolve, so too does the way we interact with and perceive our animal companions. Whether cats are truly becoming tamer or if it is our changing relationship with them that is driving this perception remains open to interpretation. What is clear is that both species are navigating an ongoing process of mutual adaptation.
