I feed my snakes every 5 days for the ones under 5-600g. Over that is every 7 days.
Cleaning is done as a daily check for deification / urates / shed (spot cleaning) and once a month full clean / cage sanitize.
I top off water every morning and do a full replacement + scrub every 4-5 days.
Aside from that, daily monitoring of temps / humidity. If one is starting the shed cycle I start the once or twice a day misting. (For the ones in tanks)
Weekly weigh-ins the day before they are fed.
Play time (more for me than the snake. They just tolerate it)
