It's fine and plant is pothos- safe.
I sometimes do the same with my panthers- they seem to prefer to lay around plant roots so I use 17" pots for their plants. The big thing to watch out for is the roots becoming too thick in time, so the female can't find a spot to dig. To prevent this, pull up your plant a couple times a year and clip the roots back and then repot in fresh dirt- good for the plant and keeps the lay site clean.
