One of the first questions new owners ask is whether to choose a male or a female cat. The honest answer: once cats are spayed or neutered, the differences are small — and individual personality, early socialization and breed matter much more. Still, there are some general tendencies worth knowing.

Intact (not neutered) cats: big differences

Before neutering, sex hormones drive behavior strongly.

Intact males (toms)

  • Spray strong-smelling urine to mark territory — indoors too
  • Roam widely in search of females, often getting into fights and traffic accidents
  • More likely to fight, which spreads FIV (feline immunodeficiency virus)
  • Develop wide "stud" cheeks and a stronger body odor

Intact females (queens)

  • Come into heat repeatedly from as young as 4–5 months, often every 2–3 weeks during breeding season
  • In heat, they yowl loudly, roll, rub against everything and try to get outside
  • Can become pregnant very young and have several litters a year
  • Have a higher risk of mammary cancer and uterine infection (pyometra) later in life

This is why vets recommend spaying or neutering for pet cats — most of these behaviors disappear or become much less likely.

Neutered cats: subtle tendencies

Owners and some surveys describe these general trends, but there are plenty of exceptions:

TendencyNeutered malesSpayed females
SizeUsually larger and heavierUsually smaller
SociabilityOften described as more laid-back and cuddlyOften described as more independent or selective
Weight gainHigher risk after neuteringAlso at risk, slightly less
Urinary blockageHigher risk (narrow urethra)Very rare
Territorial disputesCan be more boisterous with other catsCan be less tolerant of other females

What matters more than sex

  • Individual personality — spend time with the cat, or ask shelter staff about them.
  • Early socialization — kittens handled gently by people between 2 and 7 weeks of age tend to be friendlier adults.
  • Breed tendencies — a Siamese of either sex will be more vocal than a British Shorthair. See cat breeds.
  • Age — kittens of both sexes are energetic; adults are more predictable.

If you'll have more than one cat

Pairing is usually more about personality and energy levels than sex. Littermates and kittens adopted together generally get along well regardless of sex. When adding a cat to a resident cat, choosing one with a similar energy level and a different "role" (not two very dominant cats) matters more. Read one cat or two?

Bottom line: choose the cat whose personality suits you. Then spay or neuter, and most "male vs female" problems disappear.
