Well, when you bring them in for their eventual check-up, you can have your vet sex the kittens for you. Bring your sister with you so that when the vet tells you that they are, in fact, girls, you can look at your sister with a very smug look on your face and say, "I knew it! I told you so, ______________! (<---- insert sister's name)" Can't argue with the vet, right? :lol: :lol: :lol:Martho said:By the link Heidi posted, I am about 98.563282562573% sure they are girls. But my sister still thinks they are boys. I think she just doesn't want to admit I was right.
