A leopard gecko log works when it follows the gecko's ground-level life: insects hunted on the floor, sheds completed inside a humid hide, and warmth felt through the belly from below. One short entry per feed, plus a temperature line taken the same way each time, builds a record that explains appetite changes instead of just listing them.
Feed entries for a ground-hunting leopard gecko
A leopard gecko feed entry should record the insect, the count and the hunt itself. Write whether you offered crickets, roaches, mealworms or another feeder, how many were taken, and whether the gecko struck quickly or ignored prey moving right past. Note feeders removed uneaten, because loose crickets left overnight can bite a resting gecko and because a rising leftover count is often the first sign a shed is coming. Dusting belongs in the entry too: record when insects were coated, so gaps in supplementation are visible in the history rather than remembered roughly weeks later.
Shed entries centred on toes and tail tip
A leopard gecko shed entry should centre on toes and the tail tip, where retained skin causes trouble. Leopard geckos usually pull the old skin off in the humid hide and eat it, so finding almost nothing left behind is normal and worth recording as a clean shed. After each shed, check every toe for tight pale bands and note the result in the log, along with whether the eyes opened clear and bright. Skin that stays stuck after the rest has cleared, toes that look pinched, or a gecko rubbing constantly at one foot should be written down with a note to contact a reptile vet if it does not resolve promptly, rather than pulled at home.
Floor temperatures, not air guesses, for this gecko
Floor temperatures matter for a leopard gecko because it warms its belly on the ground, not by basking up high. Record the warm-side floor reading where the gecko actually lies, the cool-side floor reading, and the reading inside the humid hide if you can take it without dismantling the setup. Keep the probe in the same spots each time, because a probe moved onto a wall measures a different enclosure from the one your gecko lives in. When a leopard gecko stops eating and the warm floor reading has quietly slipped, the log shows a heating problem to fix before it shows a feeding problem to worry about.
Weight, tail and appetite read together
Weight, tail shape and appetite tell one story in a leopard gecko when the entries sit together. The tail stores reserves, so note whether it looks plump and smooth or is narrowing at the base, and weigh the gecko gently in a small tub on the same scale to confirm what your eyes suggest. A young gecko should trend upward between sheds, while a healthy adult holds steadier, with brief appetite dips around shedding that the shed entries explain. Repeated refusals outside shed time, a thinning tail and falling weight recorded together are a clear prompt for a reptile vet, and the dated pattern in your log shows how quickly it developed.
Keeping the leopard gecko record usable by someone else
Keeping the leopard gecko record usable means a sitter can follow it without a briefing call. Write feeder counts plainly, name which hide is the humid one, and note the exact warm floor reading the enclosure should show, so a helper can spot a heater failure from your numbers alone. Bringing the feeds, clean sheds, toe checks and floor temperatures together in KinsLe's Pet Passport gives that gecko one portable record that stays readable long after the notebook page would have been lost.
