She has dementia and never smells it. She will think I am being mean if I tell her she smells of urine. My sister-in-law told her she needed to change cause she smelled. and she told her NO like a child, that she does not smell. She is in total denial on everything, her cleaning days are over. I dont live with her but I come and stay for a week when I can, and it is hard eating there because of the smell. She refuses help from the outside. I am lost for words. I have 4 brothers and they said its my responsibility to tell her because I'm the daughter. When they visit they sleep outside in tents because of the smell of urine and kitty litter. She has no clue why they sleep outside. I cant give the cat away because she really loves her and would miss her badly. How can I tell her without making her mad at me.
