A corn snake that has refused food for weeks may be fasting for an ordinary reason or may be ill, and the vet separates those possibilities largely from the history you bring. Memory blurs after a fortnight of worry, so the useful work at home is recording: what has been offered, what the enclosure numbers actually are, and how the snake itself has changed. This is a reporting task, not a cue to invent new feeding tactics, because a vet working from a precise history can judge the situation far better than one working from impressions.
The Feeding History, Offer by Offer
Write down how long the refusal has lasted, counted from the last meal the snake actually took. Then list each offer since as history of what has been tried: the prey type, the prey size relative to the snake, and how it was offered, whether left in the enclosure, presented moving, or offered at a particular time of day. Record the snake's response to each offer in plain terms — ignored it, showed interest and withdrew, struck and released. This list matters twice over: it shows the vet the pattern of the refusal, and it prevents the consultation from ending in a suggestion the snake has already refused three times. Note also the last successful feed and what was taken then, since the change from eating to refusing is often where the story starts.
The Enclosure Numbers, as Measured
Report the warm-end and cool-end temperatures as measured, not as the thermostat is set, because the two can differ and the difference itself is a finding. Say where the readings were taken and with what, and whether they hold steady overnight or drift. Record the humidity the same way, as a reading rather than an impression, and note the water provision and when the enclosure was last cleaned or rearranged. Recent enclosure changes belong in this history in full: a new vivarium, a moved heat source, new substrate, a new hide, or a change of room. Snakes respond to their environment slowly and completely, and a refusal that begins in the same week as an enclosure change reads very differently from one that begins in an unchanged setup.
The Snake Itself
Weigh the snake and record the weight trend, comparing it with any earlier weights you hold, because steady weight across a fast and falling weight across the same period point the vet in different directions. Note where the snake is in the shed cycle: dull or milky eyes and a fading pattern suggest a shed approaching, which belongs in the history even though only the vet can judge its weight in the refusal. Record handling frequency honestly, including any recent increase, and note activity: whether the snake roams at night as usual, hides constantly, or has changed its routine. Look, without forcing anything, for the visible details a vet will ask about — condition along the back, the state of the mouth area if seen when the snake yawns, and any discharge, swelling, or retained shed on the tail tip or eyes.
Signs That Raise the Urgency
Some findings move this from a booked appointment to an urgent one. Weight loss you can see, especially a spine becoming visible along the back, means the fast is costing the snake condition. Mouth signs — swelling, discharge, or a mouth held partly open — and any breathing signs, such as wheezing, clicking, or bubbles at the nostrils, need prompt veterinary attention rather than more weeks of recording. A snake that becomes weak, unresponsive, or stops drinking likewise should not wait. Take the full history with you: the offers, the measured temperatures, the humidity, the shed stage, the weights, the handling, and the changes, in the order they happened.
KinsLe's Pet Passport keeps a dated record of feeds, weights, sheds, and enclosure readings, so the health history a vet needs is already assembled before you arrive.
