Okay--we're building a house with a septic system. We've been using Scott toilet paper because we can get it at a good price, and we know it won't clog up the septic at the new house. Once the house is built, my 86-yr-old mother will be living with us. When I was at her place in May, I noticed she uses the ultra-soft-mega-quilted Charmin -type toilet paper. She has hemorrhoids. Is there a softer paper than Scott that won't ruin the septic? I don't want her to be miserable.
