How Can You Tell The Sex Of A Kitten?

You cannot tell the sex of a kitten. It is impossible for you to know unless it has been fixed by surgery, which most people do not have the money or resources to get done. You can only guess at its gender based on how many kittens it had in its litter and whether they are one-eared, two-eared, etc., but there are no guarantees that more than one kitten will be male or female.
