Start with hands-on history, not enthusiasm
Plenty of sitters love animals in general and have never read a thermostat in their lives. Open by asking which reptiles they have kept themselves and which they have cared for professionally, and listen for specifics: species names, feeding routines, a shed or a hunger strike they managed. A sitter who has kept a bearded dragon will talk about basking temperatures without prompting; one who has only topped up a neighbour's goldfish will stay vague, and vagueness is your answer. Ask how many homes they visit in a day during busy seasons, because your daily check competes with that list, and ask whether the person at your meeting is the person who will actually attend every visit.
Ask the failure questions
Routine days look after themselves; you are hiring for the day something breaks. Put the scenarios plainly. The heat lamp is dark when you arrive — what do you do? The snake has refused its feed and the rat is still in the enclosure — then what? The water dish has flooded the substrate, the humidity is far above normal, there are mites on the water bowl, the animal has not moved from one spot in two visits. A good sitter answers with a sequence: make the animal safe, take a photograph, phone you, follow the written instruction, in that kind of order. A sitter who says they would wait and mention it when you get home has told you how your emergency would be handled.
Cover hygiene, security and communication
Reptile disease travels on hands and equipment, so ask what they do between homes: hand washing or sanitising before touching your enclosure, no shared tools, and whether they care for reptiles in their own home that could carry parasites or infection. If they have reptiles themselves, that is not a disqualifier — most excellent sitters do — but you want to hear that the risk is one they manage deliberately. Then the household practicalities: how keys are stored and labelled, how they handle alarm codes, whether visits are logged with times, and how updates reach you — a photograph and the day's temperatures after each visit is a fair baseline to agree on.
Watch them work before you book
The most informative part of the meeting is practical. Ask the sitter to change the water, mist the enclosure or prepare a feed while you watch. You will see confidence around the animal, whether they check the thermometer unprompted, how they move around a nervous species, and whether they wash their hands first without being asked. Note, too, how your animal responds and how the sitter reads that response. If the meeting goes well, agree a trial visit while you are away for a single day. Finding candidates through the KinsLe Pet Services Directory means the sitters you meet already present themselves as reptile-capable, so the first meeting can go straight to these deeper questions instead of starting from whether they take reptiles at all.
