Research overview: paternal genetics and boldness in kittens

A cat's temperament is shaped not only by early experience but by inheritance, and this overview surveys evidence that the father contributes to kitten boldness and friendliness. It examines studies indicating that, even though toms typically have no contact with their offspring, paternity influences how bold or shy kittens are toward novel objects and people, pointing to a heritable component of temperament. The survey discusses how this paternal effect interacts with early socialization, so that bold-fathered, well-handled kittens tend to be the most confident and people-friendly, and the implications for breeding and predicting adult sociability. It situates these findings within the broader nature-and-nurture account of feline personality, presenting boldness as a partly inherited trait that combines with early experience to determine how a cat relates to its environment and to humans.
