Help sexing 9 week old kittens

[Beejaf]

We are so confused please can anyone help us sexing these 9 week old kittens.

 

[Willowy]

All girls!

That's why it's confusing, I think. There's some natural variation, and with no boys to compare them to you start to second-guess yourself.

 

[Beejaf]

Thanks so much, so grateful for your help. Cat 4 did seem to have too much gap between the 2 holes so we were almost sure it's a boy.
Oh well, all girl household then.
