hi all,im asking for help with my 2 oldest snakes 12yr old male and 11yr old ? havent had it sexed. they have lived together all their lifes in a big enough viv, but this morning i was sat on sofa next to the viv when...they started chasing each other around it, they have not done this before?he then stopped between the side and the waterbowl and the other one got on top and was trying to wrap its tail round his but didnt look like he was giving in, i did google this and it said its the start of mating. my questions are 1.why are they doing this now after all these years...? 2.say the other is female can they start mating...? 3.i couldnt see if they 'locked' together how will i know if it worked...? and 4.will i have to seperate them if 'she' is pregnant...? many thanks
