Please clarify your temps. Are you saying the ambient temp of your whole enclosure for your bp fluctuates between 25-32 degrees celcuis? Or are you saying your cool side is 25 and hot side is 32?
IMO no matter the case, I think 25 celcius is a bit on the cool side. I keep my cool side for my bp's fluctating between 26-28, and every once in awhile it gets to 29 for short periods of time. My hot side runs 32-33 and occassionally for short periods of time 34. Those temps seem to work well for my bp's and they seem to like it.
As far as them defacating, mine have gone easily 3 weeks and longer in between. If you are that worried about that with your snake, maybe soak him/her in warm water, but remember not too deep.
