It could be a weak bladder. Keep an eye out for signs of blood, and maybe consult a vet. If she is weeing on you, then it could be "marking territory" but females arent really known to do this (though they do dribble every now and then as they walk).
"One of My girls will mark and the other will follow behind licking it up. They are just trying to get rid of the other's scent."
LOL gross!!
