Kitten gender

Hello does anybody know the gender of my kittens? There 6 weeks old. I think kitten 1 is a girl and 2 is a male based on the distance but I’m not sure. thank you. zoe 

Hello there - first a disclaimer; I would not sex kittens on the internet because it is not always straightfoward and would strongly suggest a kitten-check at your local vets, which is likely to be low-cost and gives the vet the advantage of seeing coat-colour, making a proper assessment in relation to age and picking any anomalies up, both relating to sex alongside coat-colour and also regarding picking up perinatal differences and listening to their hearts.  Kittens will also need assessing for their worming requirements.  I have two pictures here and would guess them to be boys at different stages of the development of their testes, but this is odd for littermates and I would want to see the kittens in context, so cannot offer any of the certainty that you, as their owner, will need.

Unfortunately the genital area of the top kitten is a little fuzzy and it is difficult to guage size and spacing of the two holes.   I cannot happily sex from this picture in particular.  I cannot see a third kitten.
