My mother is 94 and has had cancer for 3 years. Refused any treatment is now on crisis. And has dementia. Nursing home list which could take upwards to 6 month. My sister who lived close and had looked after for 3 years burnout and moved. Mom over feeds the cat cannot clean cat litter but refuses to rehome cat just says to put him down when she dies, no one in family is close by so alternate days but cat has already peed on rug of rental apartment feel like need to rehome this cat now but cannot get mother to co operate any suggestions could we just take the cat she mostly sleeps.
Your mother is in the last days of her life at 94 and with cancer. Don't take away the cat who is her constant companion regardless of whether she sleeps much of the time or doesn't. That's cruel. Hire someone to go to her place on the days when family members are unavailable.
No-kill animal shelter are successful in re-homing adults/senior cats. Our last two cats we adopted when they were 9 and 12 years old. They were so happy to have all the new attention =^..^=
OR
Tell mom that you noticed an "off odor" in the urine or blood in the litterbox and need to take the cat to the vet. Once that is done you can rehome the cat. (there are no kill shelters, please do not euthanize the cat unless there actually is a medical reason)
Clorox has a product called Urine Out and there is another product called Odor Ban that will be useful taking the urine and odor out of the carpet. It is possible though that carpet and possibly flooring might have to be replaced. (once urine gets into sub flooring it is almost impossible to get the odor out.)
Cats can get UTI's and start peeing in new spots. Or they will do that because of stress and changes in their envioronment.
It can help to set up a second litter pan near where they peed. Might need a vet checkup.
Someone coming in and checking on your mom daily and doing the scopping would help, if the cat's healthy.
What kind of care would your pre-illness mom want for this poor cat, who through no fault of it's own now has an ill owner incapable of empathy due to her disease and no-one to take care of it consistently? Can someone in the family adopt it?
If not, look online for local rescues- most have a precence on Facebook. Or call the local animal shelter or the vet's office and ask for names of local rescues. If you use Petfinder or Pet Tango to search in the zip code, the animals that will show up will have the names of their affiliated rescue.
