Each cat just needs someone to come in, give Rx wet food to both and mix liquid meds for one cat and pill the other cat each morning. Also, just fill auto feeders each day and check water bowls and empty litter boxes. Would not be more than 1 hour most each day and could come anytime that works, especially over the holidays. May even be okay with skipping Christmas Day, just give a little extra food in auto feeders.
