I mean filth, animal feces ground into the carpet and dried, dirt everywhere. Not to mention unsorted clutter. Mom was always very clean and neat. My sibling moved in and the house has slowly turned into a sewer - there's nothing she can do and she needs the help as she is very feeble, and won't hear any critisism of this child anyway. I live several thousand miles away. When I come to help, I feel so nauseated that I can't eat for days on end. I clean and clean-I'm not very good at it- but cannot catch up, more filth is tracked in, more grease from cooking, nothing ever washed. Cleaners have been hired but they quit in disgust. I think the sibling has a disorder that makes dirt invisible- and thinks I'm a neurotic and am "having a fit" when I (calmly) try to talk about the dirt. What can I do about this situation?
I always had a clean house, but once I had to start helping my parents at their house [I didn't do any cleaning or making things neat as Mom was still able to do that] I noticed I didn't have the energy to tackle any cleaning at my own house. I was lucky to keep on top of all of my own laundry.
Everyone has their own level of keeping things clean, and it also could be that your sibling doesn't feel this is all that important, thus her cleaning "bar" is set very very low.
Surprised the cleaning crew had quit.... usually a quality company, like Service Master, will charge an arm and a leg for the first deep cleaning, then charge less each week or half week thereafter.
You might call your local area agency on aging to inquire about services your mom may be eligible for.
Anyway... the dog pooped and peed all over the entire apartment. It smelled horrible. The stench and dog food brought in the mice, so soon the apartment was a health hazard. The mice also spread throughout the building, so we neighbors were also having problems.
The dog had Cushings, so was put to sleep a few months later. It was sad, but I saw what animals who are not properly tended can do to a house in a very short time. Your concern is very real. The animals need to go outside to do their business. If your sister can't do that, then she needs to rehome the animals. Having pets comes with a responsibility to keep the pets and the home healthy. I feel sorry for the animals and your mother. My neighbor's home was nauseating and unhealthy from one dachshund, and it only took a few weeks. I know your mother's home is even worse.
Remove carpet. Have only easily maintained floors. Someone who doesn't remove poop probably won't remove shoes. Flies will be a big problem. Your mother is living with a person who needs help herself. However, although it doesn't sound like it, you might be biased, so seek the outside help. Ask for police or sheriffs department to make a check. If you know the neighbors ask them to complain to whatever authorities are available. Your sisters denial of the drs findings on your moms illness is really distressful. That's really the worst thing you posted. You have to take action. I know it's a thankless task but necessary. At one time social stigma would have helped you. We are pretty much dependent on government intervention in the times we live in. Put your head down and move forward. Your mom is depending on you and so is your sister.
