To tell if a kitten is male or female, look under the tail at the shape of the openings and the space between them, and ask a vet if you are unsure at any point.

How to Tell if a Kitten Is Male or Female

Quick Scoop

Sexing kittens is mostly about looking at “dots and lines” under the tail, plus noticing a few bonus clues like coat color and the kitten’s age.

Step‑by‑step: Checking Safely

  1. Get the kitten relaxed
    • Gently pick the kitten up when it is calm or sleepy, not in the middle of playtime.
 * Place it on a soft towel or your lap, supporting its body so it feels secure.
  1. Lift the tail gently
    • With one hand supporting the chest or hindquarters, use the other to gently raise the tail.
 * Never yank or hold the kitten upside down by its legs or tail; that can hurt or stress it.
  1. Find the two openings
    • The opening at the very base of the tail is the anus.
    • Below that is either the penis (in males) or the vulva (in females).

Think of it as looking at a tiny “face” with two features: you’re comparing shape and distance.

Visual Trick: “Colon vs Exclamation Mark”

Many vets and breeders use a simple memory trick.

  • Male kittens (the “colon” or “dots” look)
    • Anus on top, and a small round dot (penis opening) below it.
* There is a **noticeable gap** between the anus and the dot; that gap is where the testicles sit or will develop.
* People sometimes describe this as “dots and dashes” or just a “:”.
  • Female kittens (the “exclamation mark” or “line” look)
    • Anus on top, and a vertical slit or teardrop directly below it.
* The slit is **very close** to the anus, with only a tiny space in between.
* It looks a bit like an upside‑down exclamation mark “¡” or a little “i”.

A lot of rescuers sum it up as:
“Line close to the butt = girl. Circle farther from the butt = boy. ”

Age Matters: Tiny Kittens vs Older Kittens

Sexing newborns is trickier than sexing an 8–10 week‑old kitten.

  • Newborn to ~2 weeks
    • Genitals are very small, so you mostly go by distance between openings rather than testicles.
* The gap on males can still be subtle, and mistakes are common even among experienced people.
  • Around 6–10 weeks and older
    • Male kittens often begin to show or feel two small oval testicles in the space between anus and penis.
* You might see a slight bulge or “pouch” in that area.
* Females keep a flat area with just the short slit under the anus.

If you gently pinch the space between the openings on a suspected male, you may feel two tiny “beans” under the skin; that usually means boy.

Bonus Clues: Coat Color & Litter Comparisons

These aren’t perfect, but they can help.

  • Tortoiseshell or calico kittens
    • Kittens with black/orange mix (tortie) or white + black + orange (calico) are almost always female.
* A male tortie usually has an extra sex chromosome or other rare genetic quirk, so it is very uncommon.
  • Comparing littermates
    • If you have several kittens, place two side‑by‑side and compare the under‑tail area.
* Differences in spacing and shape are much easier to see when you’re looking at more than one kitten.

When to Ask a Vet

  • If your kitten is very young and you’re not certain, ask a vet or shelter staff to check; even professionals sometimes double‑check with tiny kittens.
  • If you suspect something unusual (no clear openings, swelling, or discomfort when touched), get a veterinary exam to rule out medical issues.

Mini Story Example (for your “Quick Scoop” style)

Imagine you’ve just brought home a tiny stray fluffball. You gently settle them on a towel, lift the tail, and see two openings. They’re almost touching, and the lower one looks like a little line, not a dot. After comparing with a couple of reference photos, you realize that you’re looking at the classic “exclamation mark” pattern, so you can confidently start brainstorming girl names for your new roommate.

TL;DR:
Lift the tail, look underneath: circle with a gap = usually male , short line almost touching the anus = usually female , and if you’re unsure, let a vet confirm it for you.
