I scooped my sand out with cups as much as I could and then when I couldn't scoop anymore I took a vacuum to it and got the rest up. Continue what you are doing with the baths and the the oils and prunes. Oh, PUMPKIN is real good too either fresh or canned. If you get canned make sure it's pure pumpkin and not pumpkin pie filling since the filing has spices added to it.
What kind of sand did you use? If you used calci sand I would take him to the vet and see if there is anything they can do sometimes they can give an enema. The issue with calci sand (besides my spell check keeps wanting to change it to calico) is calcium is binding. Think about what happens when your dusting your feeders and the calcium gets wet, it sticks and when you go to wash that cup or bowl out you have to scrub a little to get it out. Another analogy is clumping cat litter when it gets wet and it becomes a big hard lump. Now imagine this in your intestines.
