Companion Care Needed

We need companion care to take care of our 87-year-old mother in Clarence. We are looking for 3 days a week to start, midday to afternoon hours. No weekends. Some light housekeeping would be appreciated. Seeking someone to handle small meal preparations. Duties include providing companionship and social interaction. Will need the handling of groceries or errands when appropriate. Preferences for a caregiver who is a non-smoker, comfortable with cats and CPR / first-aid trained.
