What sex is this kitten

the kitten is about 7 weeks

I'll move your post to the Kitten care forum.  There should be someone in this forum who can advise you.

Welcome,
Is this you new kitten?
It can be difficult to determine a kittens gender.
This cutie looks old enough that someone with experience should be able to tell.
Stick around, we have all kind of info about how to raise a kitten.
Make yourself at home.:rub:

Female.

A girl

It looks like our members agree that you have a little girl....
she is adorable. :lovegrin2
Is her name Otis?
Now that you know her gender, you are welcome to go back to our New Cats on the Block forum and introduce yourself and your sweet kitten to our members.

I have to concur.  It looks like a female to me.

No her name isnt Otis, Otis is my 2 1/2 year old dachshunds name, the baby kitty doesnt have a name .

I just know that you will find the perfect name for her.

She's adorable! 

I have dachshunds as well - a mini blk/tan broken coated long that's 5 (Sadie), a standard choc/tan brindle broken coated long that's 3 1/2 (Fynn) and a standard blk/tan long that's 2 1/2 (Lucy, but she doesn't live with me).
