Is it a boy or a girl, that's a real problem!

One day, our kittens were in a very good positions, so i took some butt-pics...

Girl first

age 1 week

Age about 6 weeks

Then a boy

age 1 week

Age about 6 weeks

And them both in age of 6 weeks


It isn't always this easy to say, what is the sex of kittens, but i hope someone gets some help of these pics.. ;)
