male or female kitten?

[npg1]

Opinions please, due to get a kitten in a few weeks, not sure if I want a male or female and would like to hear from other people.

Well the girl accross the road(who works in a vets) came over and the kitten is about 4/5 weeks she think because he is getting his teeth and she says he look really healthy, and cute So Lucky he is, as he survived a bin lorry compacter!
