Female vs male cats: is there really a difference?

Is there a real personality difference between male and female cats?

Male cats are typically believed to be more affectionate than female cats who tend to be more independent or aloof. Research has found that sex doesn’t determine personality. Individual temperament, genetics, and experiences between two and seven weeks of age influences how affectionate or confident a cat becomes.

A kitten that is gently handled by humans during this window is more likely to grow into a sociable adult, regardless of whether they are male or female.

Some owners do report noticeable differences between their own male and female cats. While this isn’t wrong, it simply reflects those particular cats rather than their gender overall.

Why neutering matters more than sex

The biggest behavioural differences are usually between neutered and unneutered cats, not between males and females.

Unneutered male cats are more likely to roam, fight, and spray strong-smelling urine to mark their territory.

Unneutered female cats may become more vocal and restless when they come into season, sometimes seeking out extra attention during this time.

Neutering reduces these hormone-driven behaviours in both sexes, and is one of the most effective ways to help any cat settle into a calmer routine.

Physical differences between male and female cats

Male cats tend to be slightly larger and heavier than females of the same breed, with broader heads once they reach adulthood.

Female cats are more likely to have tortoiseshell or calico colouring, as the genetics behind these patterns are linked to the X chromosome.

Male cats have testicles, located in the scrotum beneath the tail, until they are neutered. During castration, the testicles themselves are removed, though the scrotum remains and gradually shrinks over time, which can sometimes make it look as though a neutered cat still has testicles.

Occasionally, a male cat’s testicles fail to descend into the scrotum – a condition called cryptorchidism. These cats still need neutering, as retained testicles continue producing hormones and carry a higher risk of cancer if left in place.

Does a cat’s sex affect how they bond with their owner?

There is no way of proving that female cats prefer male owners, or that either sex bonds more strongly with a particular type of person. A cat’s attachment to their owner depends on the relationship built between them – consistency, gentle handling, and positive experiences matter far more than anyone’s gender. The same applies in reverse: a cat’s own sex does not determine who they choose to bond with.

If you are choosing between two cats and want to keep them together for life, neutered cats of either sex generally get along just as well with one another. It depends more on the individual cats and their personalities than on their sex. Being bonded as kittens does not always guarantee they will keep that close friendship as they grow up.
