What Is My Kitten’s Gender

If you’ve established a good relationship with the cat, pick him or her up and lift its tail. If the kitten isn’t responding well, you may want to solicit the assistance of a friend or family member. If the cat still isn’t lifting its tail, try scratching it where the lower back meets its tail most cats lift their tails if you do this to them.

What To Look For To Determine The Gender Of A Kitten

The most obvious first step to find out the gender of a new cat is to look under their tail. This is easier to do with short-haired kittens, so you may have to comb away any extra fur if you are examining a long-haired kitten. Make sure the kitten is lying flat on a towel and lift the tail gently to avoid injuring the animal. Never lift a kitten up by the tail!

Male Cat Sexual Behavior

Unfixed males will also engage in behaviors that you may find annoying to deal with, and these can begin as young as six months. Even male cats that have been fixed may continue to engage in these behaviors if they were fixed later in life. Typical mating behaviors of male cats are:

  • Spraying urine to mark their territory, which unfortunately means your home

  • A greater propensity to roam and want to be let outside if they sense female cats in heat nearby

  • Fighting with other cats, whether it’s other males in the home or neighborhood cats if your cat goes outside

  • Howling or caterwauling if a female in heat is nearby

  • Scratching behavior may increase more when a male cat is stimulated by the presence of a female cat in heat

  • You may also notice mounting behavior from a male cat toward toys, other cats, or even your leg. This can happen when an unsterilized male is aroused by the scent of a female in estrus.
