My mom is 84 yrs. old in declining health. She has arthritis, asthma, hard of hearing, bad eyesight, slow shuffling walk, high blood pressure etc. etc. She cannot even open a can of tuna or turn a bottle cap. My niece wants to give her a cat. My mom wants to keep it in her bedroom. My mom cannot even take care of herself. I am my mother's legal caregiver. Do I have the right to refuse this cat into the house?
