Animal Care Needed

2 older cats. Kitty and Buddy. Kitty is on special food for kidneys and Buddy takes meds on his ears for thyroid in the morning and evening. We are thinking of leaving our cats with our mother who lives in Apopka Fl and has a cat of her own. But she is 95 and we don't want her taking on the responsibility of caring for them. But we want them to have her company as they get anxiety when alone. My sister in law lives directly across the street and people are always stopping by to check on her. She is a very good 95, So many times when you go buy someone might be there beside my mother in law. So want you to be comfortable.
