Caregiver Needed

I'm looking for household/pet care for my grandmother in her 80s. Ideally 2 days per week for a few hours- schedule is flexible. My grandmother has 4 cats and lives alone in a 3 bed/2 bath mobile home in a gated community. Primary needs include cleaning cat water fountains, changing cat litter, and performing light household tasks such as organizing or sorting through items alongside her (would not require skilled labor or heavy-lifting). Please be willing to do light housekeeping as needed (she has a monthly house cleaner for deep cleaning). Must be comfortable with cats and willing to provide references.
