A sulcata is not a short project. This is a giant, long-lived tortoise that will keep growing for many years and may eventually need several adults to move it, so its records need to survive longer than any single notebook, phone, or keeper's memory. Build the file around slow change: growth measured patiently, shell condition photographed honestly, and the seasonal routine written down while it still feels obvious.
Weight, length, and shell photographs
Weigh your sulcata on a schedule it can tolerate and record straight shell length at the same time, always noting whether the weighing happened before or after a long graze or soak, since both shift the number. In a young tortoise you are watching for steady gain; in a mature animal you are watching for drift in either direction. A sudden drop deserves attention, and slow unexplained gain in an adult that is no longer growing can point back to rich feeding.
Photograph the shell from above, from the side, and from underneath if it can be done safely, in similar light each time. Dated photos reveal smooth versus raised, pyramided growth far more reliably than daily glances do, and they document knocks, scrapes, and the wear patterns of an animal that pushes against fences and furniture. Keep early photos from acquisition onwards — the comparison ten years later is the point.
Food, grazing, soaks, and seasons
Log what the tortoise actually eats, not the menu you intended: hours of grazing on untreated grass, the grasses and weeds offered, hay accepted or ignored, and any rich foods that slipped in as treats. Sulcatas are grassland grazers, so a record dominated by grazing and coarse, fibrous food tells a healthy story, while a log quietly filling with fruit and soft foods explains shell and weight changes. Note soak frequency and how the tortoise drinks, plus droppings and the white urates passed, since changes there can reflect hydration and diet.
Record the seasonal machinery too: the outdoor temperatures at which you brought the tortoise in, the heated shelter setup used through cold spells, and the dates it returned to full outdoor living. A future keeper, house-sitter, or family member inheriting winter duty needs those thresholds written, not remembered.
Vet history and the succession page
File every vet visit, beak or nail trim, test, and piece of advice, and keep origin details: where the tortoise came from, its estimated age, and any earlier history. Then add a page most tortoise files lack — succession. Name who would take the sulcata if you could not keep it, who can help lift and transport it, and where its heated housing instructions live. An animal this long-lived is a commitment other people will share, and honest records are how they share it well.
Contact a vet if weight falls without explanation, the tortoise stops grazing in warm weather, breathing sounds noisy, or shell damage breaks through to soft tissue, and take the growth and feeding log with you. Gathering all of it in KinsLe's Pet Passport holds your sulcata's records together in one portable packet that can travel with the tortoise to any vet, helper, or future home.
