Breeding kings.

Question
My King Snakes don't seem to have any interest in each other when i introduce them anymore, they did breed several times.. do they have pheromones? Maybe when the get pregnant they don't send out the pheromones anymore? When i was putting the male in before he would go almost right to her, and now he ignores her.. is this a sign she's pregnant?

Answer
yes, female snakes release pheromones when they are ovulating. Most likely she is already pregnant if the male's sperm was fertile. Feed her as much as she'll eat during this time, and make sure that she always has clean water. There's nothing more to be done by the male if she is now refusing him.
