How to Identify Your Cat’s Gender When It Arrives at Its New Home

Bringing a new kitten or cat home is an exciting moment! But one of the first questions many new pet owners ask is: is it a boy or a girl? Unlike dogs, where gender is often more obvious, determining a cat’s sex can be a bit tricky, especially when they are young.

If you’ve just welcomed a furry little friend and want to find out their gender, don’t worry! In this guide, we’ll walk you through simple steps to check your cat’s sex without stress—for you or your feline companion.


1. When Can You Identify a Kitten’s Gender?

Newborn kittens are incredibly tiny, and their genitalia aren’t fully developed, making it harder to determine their sex. Ideally, you should wait at least 3 to 4 weeks before trying to check. By this age, the differences become more noticeable, and you can have a better idea of whether you have a male or female kitten.

That said, an experienced vet or breeder may be able to identify the gender earlier, but for most cat owners, a little patience goes a long way!


2. Step-by-Step Guide to Checking Your Cat’s Gender

Step 1: Make Sure Your Cat is Comfortable

Before you start, make sure your cat or kitten is calm. It’s best to do this in a quiet, comfortable space, preferably when your cat is relaxed or sleepy.

  • Pick them up gently, speaking softly to avoid stress.
  • If your kitten is squirmy, you might want to ask for an extra pair of hands to help.
  • Always be gentle—your cat should feel safe, not restrained.

Step 2: Lift the Tail Gently

A cat’s genitalia is located just under the base of the tail. You’ll need to lift the tail gently to get a clear view. Some cats naturally lift their tail when you pet their lower back, which can make this easier.

  • Tip: If your cat is reluctant to have its tail lifted, try petting the area first to encourage relaxation.

Step 3: Observe the Genital Area

Now, here’s where the differences between male and female cats become apparent:

🐱 Male Cats (Tomcats):

  • Have a round opening (anus) followed by a second, circular genital opening below it.
  • The two openings are spaced apart, usually about 1 inch (2.5 cm) for adult cats and slightly less for kittens.
  • Testicles may be visible in older kittens and adult males, even if they are small.

🐱 Female Cats (Queens):

  • Have a round anus with a vertical slit just below it (the vulva).
  • The two openings are closer together compared to males.
  • The genital area forms more of an “i” or exclamation mark shape rather than the circular “:**” seen in males.

3. Other Clues to Determine Your Cat’s Gender

If you’re still unsure, here are some extra signs that might help:

🐾 Coat Color Can Offer a Hint

  • Calico or Tortoiseshell Cats (Three-Colored Fur) → Almost always female (due to genetics).
  • Orange or Ginger Cats → More likely to be male, though females can also have this color.

🐾 Behavior Differences

  • Male Cats (especially unneutered) tend to be more territorial, may spray urine, and are often more affectionate with humans.
  • Female Cats are typically more independent and may show signs of heat (calling, rolling) if unspayed.

4. Still Not Sure? Ask a Vet!

If you’ve tried everything and still aren’t 100% sure about your cat’s gender, your vet can confirm it in just a few seconds. A quick check-up is also a great opportunity to discuss neutering/spaying options, which is important for your cat’s health and behavior.


Boy or Girl, Your Cat is Purrfect!

No matter if you have a boy cat or a girl cat, what really matters is giving them a loving and caring home. While identifying your cat’s gender might seem challenging at first, with a little patience and observation, you’ll soon be able to tell!

And now that you know, it’s time to pick the perfect name—happy cat parenting! 🐾😻
