What is the Difference Between Male and Female Cats?

🆚 Go to Comparative Table 🆚

There are several differences between male and female cats, including their genitalia, appearance, behavior, and personality. Some of the key differences are:

  1. Genitalia: The main difference between male and female cats is their genitals. Male cats have testicles and a penis, while female cats have a shorter distance between the anus and the vulva (which appears as a slit).
  2. Appearance: Male cats are usually slightly larger than female cats, particularly if they were not neutered before they reached sexual maturity at around four months old. Unneutered males or males neutered later in life typically have rounder faces with bigger cheeks due to their testosterone.
  3. Behavior: Male cats tend to be more social and playful, often forming strong bonds with both humans and other cats. Female cats, on the other hand, are generally more independent and may be more affectionate than male cats.
  4. Territorial Marking: Urine marking is more common in male cats, especially when they are unneutered.
  5. Indoor/Outdoor Time: Male cats have outdoor territories that are almost three times larger than female cats.
  6. Aggression: Intact female cats can be more aggressive than spayed females and neutered males, but this is not exclusive to females.
  7. Life Expectancy: Research published in the Journal of Feline Medicine and Surgery in 2015 found that male cats tend to have a slightly shorter life expectancy than female cats.

When choosing a cat, it's essential to consider the personality you would like your new feline friend to have, rather than focusing solely on whether they are male or female.
