Hi I got a 5 year old female leopard gecko and it seems the right side of her vent is swollen up a bit. Ive seen her lick it sometimes. She just recently pooped and it looked normal. Her diet is mostly meal worms and wax worms. The substrate is just paper towel. Ive also seen her rub her belly and tail against the objects in her cage. She still eats and is quite active when doing so. Any help to diagnose this problem will be much appreciated.
