This is not a once-per-day visit but a 3-day-interval visit during the two months we are away. The cats have automated water and food dispensers and a litter robot so need a visit every 3 days to top-up water and food and to empty the litter robot and top-up the litter level as necessary. They may or may not want to socialise, depending on how they feel, so most/all visits might be no more than 15 minutes work.
