Both of my in laws are on dialysis and so they both have bad kidneys which has them on certain pills that makes one of them constipated and the other one have diarrhea. They're both wearing depends [such a lifesaver]..but there are times where the diaper doesn't get all of it. The problem is their room and the hallway leading to the bathroom is ALL carpet and sometimes the poop goes down their leg and unto the floor. We live in a rented apartment so my husband and I are constantly on our knees trying to get these stains out. But it seems like whenever we somehow do manage to get the stains out, another one has an accident. Now my MIL is having her toe amputated due to an infection eating away at the bone and she'll have to be off her feet for 3+ weeks. She's the one who gets diarrhea while on these meds. Meds can't be stopped as they help keep her phosphorous levels down from the food she eats. Stubborn and head strong woman so not giving her the foods she wants to eat sometimes is out of the question [I've been lying to her telling her the supermarket sold out of the meat or something]. I need to know any ways to protect the flooring for easy clean up AND keeping the carpet clean..or attempt to. I've been thinking of floor runners but they're both on walkers, too. She is legally blind on one eye and her retinal detachment on the other eye is super blurry due to diabetes and her husband has dementia problems so if they get caught their walkers caught in the floor runners they might trip while my husband and I are asleep. Any suggestions?
