Photograph everything before you unplug it
A vivarium looks simple until you rebuild it from memory in an empty room at midnight. Before the move, photograph each setup from the front, above and behind: where the thermostat probe sits, how the cables route, which socket feeds what, the exact basking arrangement. Label every plug and cable as you pull it, and bag each enclosure's fittings together with its name on the bag. Your future self, tired and surrounded by boxes, is the person these photographs are for, so take more than you think you need.
Pack the vivariums as empty shells
Glass enclosures travel badly full. Empty the water bowls, lift out loose rocks, branches and hides, and remove or bag deep substrate, which adds the weight that cracks seams when a tank is carried tilted. Pad the corners, keep tanks upright, and never let a remover stack boxes on top of a vivarium, however sturdy it looks. Heat mats stuck to glass deserve a decision: peel and replace, or protect the glass face with board so nothing presses on the element during the journey.
Animals travel with you, in tubs
On the day, each animal goes into its travel tub, bagged snakes, boxed lizards, frogs in damp-lined containers, and rides in your car, last out of the old house and first into the new one. The removal van is no place for a living animal: unheated, rattling, and loaded by people who cannot know what is inside a box. If the move spans two days, the tubs stay with you overnight in the quietest corner of wherever you sleep, temperatures checked before bed and on waking.
Rebuild one room, in the right order
Choose the reptile room's final position before the van arrives, because enclosures are miserable to move twice. Rebuild one enclosure completely, substrate, decor, water, lights and thermostat, and let it run until its temperatures have held steady, then settle that animal and move to the next. Work species by species rather than half-finishing everything. Keep the room's door closed against movers, children and escaping heat, and tape a note on it: live animals, do not prop open.
The settling week
Expect the move to show in behaviour for a week or more: hidden animals, refused feeds, a snake that soaks more than usual. Hold handling to essentials, keep the light cycle boring and regular, and weigh or note condition at the start of the week so that looking thinner is a comparison, not a worry. Call your vet, ideally the new local exotics vet you registered with before the move, if refusals stretch past the point that species normally shrugs off. Listing the move's jobs in KinsLe Care Teams, each ticked off with its time as the day went, is what stops a vivarium being forgotten in the chaos of boxes.
