Give the ball python's warm and cool targets as numbers
A ball python sitter needs figures they can check, not instructions to keep things warm. Write the warm side as the high eighties to low nineties Fahrenheit, measured at floor level inside or just outside the warm hide where the snake actually lies, and the cool side as the upper seventies to around eighty. Explain that this gradient is the whole system: the ball python moves between the two ends to regulate its own body temperature, so a sitter who heats the entire enclosure evenly has removed the snake's only control. Add the reading that should worry them, such as a warm side that has dropped into the seventies or climbed well above the low nineties, and what to do first, which is check the thermostat and call you rather than improvising extra heat.
Explain the thermostat, probe, and heat source rules
Thermostat instructions prevent the commonest ball python heating accident. State that the heat mat or radiant panel runs through its thermostat at all times, that the probe sits secured at the warm end where the snake rests and must not be taped loosely where it can slip and read the wrong spot, and that no additional lamp, mat, or heat rock is ever added, because unregulated heat sources burn snakes that cannot judge a hot surface well. Show the sitter the thermostat display and what its set point reads. If a bulb or mat fails, the instruction is to keep the enclosure closed to hold warmth, note the thermometer readings, and contact you or the named vet, not to substitute a household heater pointed at the glass.
Set the light cycle ball pythons actually need
Lighting for a ball python is about rhythm, not brightness. Explain that this nocturnal species requires no basking lamp and no special UVB fitting in most home setups, but it does need a believable day and night: ordinary room light or a low lamp on a timer during the day and real darkness at night so the snake emerges to explore and feed on its natural schedule. Tell the sitter not to leave a bright white light burning overnight to watch the snake, and if a night viewing light exists in your setup, name its colour, its switch, and when it goes off.
Tie humidity checks to the heating routine
Heating and humidity fail together in a ball python enclosure, so the sitter's instructions should link them. Warm air and a water bowl over or near the warm side drive evaporation, and a sitter topping up water is also maintaining the mid-range humidity this species needs, rising higher when the snake's eyes turn blue before a shed. Ask them to mist the warm end lightly or dampen the substrate corner you specify if the hygrometer falls, and to tell you about a shed that comes away in pieces, since that usually means the humidity slipped while the heat stayed high.
Leave a one-page check routine at the enclosure
One page, kept at the ball python's enclosure, turns heating instructions into a daily habit. Ask for a morning glance at both thermometer readings and the thermostat display, an evening confirmation that the night drop has not taken the cool side too low, and a note of anything out of range with the time it was seen. Include your number, the vet's number, and the location of the spare thermometer and fuses or bulbs your setup uses. Handing that page over as part of a single sitter handover is what KinsLe Care Pass is designed for with a ball python, giving the sitter temporary clear access to the temperatures, lighting rhythm, and fault steps until you are home.
