Hi,
I have 2 cats that are 4 and 6. They have no special needs. I have an automatic litterbox and feeders so the check-ins would require the following:

-Visit every other day or every 2 days
-Play/pet for 30 minutes
-Split a churu between them
-Refill water fountain and bowl
-Check litter box to ensure it is clear and working
-Send a picture of them every visit

If there is an issue with the litterbox I will provide special instruction (it is a litterbox 3 and has troubleshooting available online).
