please dont laugh, but ive a 5ft female Boa, who has not had a pooh since i have had her, 2 months!
so, after baths, and letting cruise around to pass some i had no luck, so i had an idea..
i wondered if i removed her water bowl for 2 days, and then put it back in with fresh, cold water, she would drink more, and flush her out..
i knew 2 days would be fine without water, and it worked!!!
Last night she was drinking, and this morning i woke to see a MASSIVE pooh.
she is FAR more active now, and seems alot happier.
