Cat sitting rates

Hello! Is $55 reasonable for a once-a-day drop-in visit to feed five cats and scoop the litter boxes? We have no other pets. Our cats are older, super chill, and don't play much. Two of them don't want interactions with anyone except me. Is this too high or about average?

Do rates go up if one potentially needs medicine? We have a second person who can stop by and do the medicine for free, but they can't come twice a day; hence, I was trying to find someone to come for an additional visit.

I’d really like to have someone visit twice a day instead of just once, but the cost seems high or maybe I’m just not familiar with typical pet-sitting rates.

Thank you for any advice!
