Reptile Care for Pet Sitters: A Complete Guide

Why Reptile Sitting Requires Specialised Preparation

Unlike dogs and cats, reptiles are ectothermic (cold blooded), meaning they depend entirely on their environment for body temperature regulation. A pet sitter who mismanages a thermostat setting or forgets to turn on a UVB bulb can compromise a reptile's digestion, immune function, and overall wellbeing within hours. Pet Sitters International (PSI) guidelines recommend that sitters caring for exotic species receive a detailed written care sheet from the owner, ideally supplemented by a walk through visit before the sitting assignment begins.

This guide focuses on three of the most commonly kept reptile species: bearded dragons (Pogona vitticeps), leopard geckos (Eublepharis macularius), and corn snakes (Pantherophis guttatus). Each has distinct husbandry requirements that a responsible pet sitter must understand.

Understanding Temperature Gradients

What Is a Temperature Gradient?

A temperature gradient is an enclosure setup that provides a range of temperatures from a warm basking zone on one end to a cooler zone on the opposite end. This allows the reptile to thermoregulate by moving between zones. Maintaining an accurate gradient is arguably the single most important responsibility a pet sitter has when caring for reptiles.

Bearded Dragons

Bearded dragons require the widest temperature gradient of the three species covered here. Professional husbandry guidelines typically recommend:

• Basking spot: approximately 38 to 43 °C (100 to 110 °F)
• Warm side ambient: approximately 29 to 32 °C (85 to 90 °F)
• Cool side: approximately 24 to 27 °C (75 to 80 °F)
• Nighttime drop: temperatures can safely fall to around 18 to 22 °C (65 to 72 °F)

Pet sitters should verify thermometer readings at both the warm and cool ends at every visit. Digital probe thermometers or infrared temperature guns are far more reliable than stick on dial thermometers, which can be off by several degrees.

Leopard Geckos

Leopard geckos are crepuscular and use belly heat for digestion, so an under tank heater or overhead heat source directed at one end of the enclosure is standard:

• Warm side floor temperature: approximately 30 to 32 °C (86 to 90 °F)
• Cool side: approximately 22 to 25 °C (72 to 77 °F)
• Nighttime: no lower than about 18 °C (65 °F)

Overhead heating is increasingly recommended by reptile veterinary professionals, as under tank heaters can create hotspots if not regulated by a thermostat. Pet sitters should confirm that any heating element is connected to a thermostat and that the thermostat is functioning correctly.

Corn Snakes

Corn snakes are generally tolerant of moderate temperature ranges, but a gradient remains essential:

• Warm end: approximately 28 to 30 °C (82 to 86 °F)
• Cool end: approximately 21 to 24 °C (70 to 75 °F)
• Nighttime: a slight drop is acceptable, but temperatures below 18 °C (65 °F) should be avoided

During cooler months, pet sitters should be especially vigilant if the home's central heating is reduced while the owner is away, as ambient room temperature drops can drag down enclosure temperatures.

UV Lighting Schedules

Why UV Matters

Ultraviolet B (UVB) radiation enables reptiles to synthesise vitamin D3, which is essential for calcium metabolism. Without adequate UVB exposure, reptiles can develop metabolic bone disease (MBD), a painful and potentially fatal condition. UVA light also plays a role in appetite regulation, activity levels, and colour perception.

Bearded Dragons

Bearded dragons have the highest UVB requirement of the three species discussed. Veterinary and herpetological guidelines generally recommend:

• A high output UVB tube (such as a 10 to 12 percent UVB bulb) spanning roughly two thirds of the enclosure length
• A photoperiod of approximately 12 to 14 hours of light per day during warmer months, reduced to around 10 to 12 hours in winter
• UVB bulbs should be replaced according to the manufacturer's recommended schedule (typically every 6 to 12 months), as UV output degrades before the visible light dims

Pet sitters should note whether the lights are on a timer. If not, the sitter must manually switch them on and off at consistent times. Irregular light cycles can disrupt circadian rhythms and contribute to stress.

Leopard Geckos

Historically, leopard geckos were kept without UVB lighting. However, recent veterinary consensus is shifting toward providing low level UVB (around 2 to 7 percent output) for improved vitamin D3 synthesis and overall wellbeing:

• A low output UVB source is recommended but should include ample shaded retreats so the gecko can self regulate exposure
• A photoperiod of roughly 12 hours of light and 12 hours of darkness is standard
• If the owner does not use UVB, vitamin D3 supplementation through dusted feeder insects becomes critically important

Corn Snakes

Corn snakes do not strictly require UVB supplementation if they receive adequate dietary vitamin D3. However, some keepers provide a low output UVB source as enrichment. Key points for sitters:

• Maintain whatever lighting schedule the owner has established
• A consistent day and night cycle of approximately 12 hours on, 12 hours off is typical
• Never leave bright lighting on 24 hours a day, as this causes significant stress in snakes

Feeding Intervals and Nutrition Basics

Bearded Dragons

Bearded dragon diets shift substantially with age:

• Juveniles (under 12 months): primarily insectivorous, typically fed appropriately sized live insects (such as crickets or dubia roaches) once or twice daily, with finely chopped greens offered daily
• Adults: primarily herbivorous, with roughly 70 to 80 percent of the diet consisting of leafy greens, vegetables, and occasional fruit, and the remainder being insects offered a few times per week
• All feeder insects should be gut loaded (fed nutritious food before being offered) and dusted with calcium powder at most feedings, and with calcium plus vitamin D3 powder at a reduced frequency

Pet sitters should never leave live insects loose in the enclosure overnight, as uneaten crickets can bite a sleeping reptile. For broader guidance on adapting feeding strategies for different conditions, our article on Feeding Dogs in Extreme Heat: A Nutrition Guide discusses how environmental temperature affects metabolism and appetite across species.

Leopard Geckos

Leopard geckos are insectivores:

• Juveniles: fed daily, typically small crickets, mealworms, or dubia roaches
• Adults: fed every two to three days, with portion sizes adjusted to the individual gecko's body condition
• Insects should be dusted with calcium powder at every feeding and with a calcium plus vitamin D3 supplement at a reduced frequency (owners should specify the schedule)
• A small dish of plain calcium powder is often left in the enclosure for voluntary licking

Leopard geckos store fat in their tails, so a plump tail generally indicates good body condition. A visibly thin or stick like tail is a warning sign that warrants contacting the owner and potentially an exotics veterinarian.

Corn Snakes

Corn snakes eat whole prey items, almost exclusively rodents:

• Juveniles: one appropriately sized pinky or fuzzy mouse every 5 to 7 days
• Adults: one appropriately sized mouse every 7 to 14 days
• Prey items should be pre killed (frozen and thawed), never live, to prevent injury to the snake
• Thaw frozen prey in warm water (never a microwave) and offer it at roughly body temperature using tongs
• Do not handle the snake for at least 48 hours after feeding to avoid regurgitation

Owners commonly pre portion frozen prey and leave it clearly labelled in the freezer. Pet sitters should confirm the feeding schedule, prey size, and thawing instructions during the pre visit consultation.

Signs of Stress in Reptiles

Reptiles do not display stress the way mammals do. Recognising subtle behavioural and physical cues is critical for a pet sitter.

Bearded Dragons

• Black beard: darkening of the throat area is the most recognisable stress signal
• Glass surfing: repeatedly scratching or running along the glass walls of the enclosure
• Gaping without basking: if the dragon holds its mouth open away from the basking spot, it may indicate overheating or respiratory distress
• Lethargy and appetite loss: while brumation (a natural dormancy period) can cause reduced activity, sudden lethargy outside of normal brumation season warrants veterinary attention
• Colour changes: persistent dark colouration across the body may indicate chronic stress or illness

Leopard Geckos

• Tail waving: slow, deliberate tail waving can signal defensiveness or agitation
• Vocalisation: squeaking or chirping when approached usually indicates the gecko feels threatened
• Refusing food for more than two weeks (in adults): may indicate stress, illness, or inadequate temperatures
• Excessive hiding: while leopard geckos are naturally secretive, never emerging even at dusk may suggest a problem
• Dropped tail: leopard geckos can autotomise (drop) their tails under extreme stress; this requires immediate veterinary consultation

Corn Snakes

• Defensive postures: an S shaped striking pose, hissing, or rapid vibration of the tail tip
• Musking: releasing a foul smelling secretion when handled, which indicates fear or stress
• Regurgitation: bringing up a meal, often caused by handling too soon after feeding or incorrect temperatures
• Repeated escape attempts: persistent pushing against enclosure openings suggests environmental dissatisfaction
• Prolonged refusal to eat: while corn snakes can safely go several weeks without food, refusal beyond the expected feeding interval should be logged and reported to the owner

How to Find and Vet a Trustworthy Reptile Sitter

Not every pet sitter is equipped to care for reptiles. Pet owners should look for the following when selecting a sitter for their scaled companion:

Green Flags

• The sitter asks detailed questions about enclosure setup, temperatures, and feeding schedules before accepting the job
• They request or offer a pre visit walk through to familiarise themselves with the equipment
• They carry pet sitting insurance that explicitly covers exotic animals (for more detail, see What Pet Sitting Insurance Should Cover)
• They hold or are pursuing PSI, NAPPS, or equivalent professional certification
• They can identify basic reptile husbandry equipment (thermostats, UVB fixtures, misting systems) and understand their function

Red Flags

• The sitter claims extensive experience but cannot explain the difference between a heat mat and a basking lamp
• They suggest handling the reptile frequently "to keep it socialised" without understanding species specific handling limits
• They have no emergency plan or are unaware of any local exotics veterinarian
• They dismiss the importance of timers, thermostats, or lighting schedules as "optional"

What to Prepare Before Leaving Your Reptile

Owners can dramatically reduce the risk of husbandry errors by preparing thoroughly. A best practice checklist includes:

• Written care sheet: a clear, printed document covering daily routines, temperatures, feeding details, supplement schedule, and handling guidelines
• Equipment orientation: walk the sitter through every piece of equipment, including thermostat controls, timer settings, and misting systems
• Pre portioned food: for snake owners, label frozen prey items with dates and sizes; for insectivore owners, arrange a reliable feeder insect supply
• Emergency contacts: provide at least two contacts: the nearest exotics capable veterinarian and a secondary emergency clinic
• Backup equipment: a spare heat bulb and a spare UVB bulb can prevent a crisis if a bulb fails mid sitting period
• Photo references: photos of the correct thermostat readings and enclosure setup help the sitter verify that conditions are as they should be

For owners of other small animals who need similar preparation guidance, our Safe Outdoor Rabbit Enclosure: A Spring Checklist and Spring Grooming for Pet Guinea Pigs: A Full Guide offer useful checklists for additional species.

Emergency Contact Protocol

Reptile emergencies can escalate quickly. A reliable protocol should include:

• The name, address, and phone number of the nearest veterinarian who sees reptiles (not all veterinary clinics accept exotic patients)
• A written authorisation from the owner granting the sitter permission to seek emergency veterinary care
• A clear spending threshold or payment arrangement for emergency treatment
• Contact details for the owner, including time zone information if they are travelling internationally
• A backup contact (a friend, family member, or fellow reptile keeper) who can assist if the owner is unreachable

PSI professional standards emphasise that emergency plans should be documented in writing and agreed upon by both the owner and the sitter before the assignment begins.

Special Considerations for Medically Complex Reptiles

Some reptiles have ongoing health conditions that require extra vigilance:

• Reptiles on medication: some bearded dragons with conditions like adenovirus or parasitic infections may be on medication schedules. Sitters should receive precise dosing instructions and, if possible, a demonstration from the owner
• Reptiles recovering from metabolic bone disease: these animals may have specific calcium supplementation requirements and need careful monitoring
• Elderly or rescue reptiles: older bearded dragons and rescued corn snakes may have reduced appetites or mobility limitations. Their baseline behaviour should be clearly communicated so the sitter can identify deviations
• Reptiles in shed: shedding (ecdysis) is a normal process, but retained shed, especially around the eyes and toes, can lead to complications. Sitters should know how to maintain appropriate humidity levels to support healthy shedding

Handling Guidelines for Pet Sitters

A general rule for reptile sitting: handle only when necessary, and always follow the owner's instructions. Additional guidelines include:

• Wash hands before and after handling any reptile (both for the animal's safety and to reduce zoonotic risk, particularly from Salmonella)
• Never grab a leopard gecko by the tail
• Support a bearded dragon's full body, including the legs and tail
• Avoid handling corn snakes during shed or within 48 hours of feeding
• If the reptile shows defensive behaviour, return it to the enclosure calmly and try again later, or simply leave it undisturbed

Final Checklist for the Professional Reptile Sitter

• Verify temperature gradient readings at every visit using reliable instruments
• Confirm UV lighting turns on and off at the correct times
• Follow the feeding schedule precisely, including supplement dusting
• Log every visit: temperatures recorded, food offered, food consumed, water refreshed, and any behavioural observations
• Photograph the enclosure setup at each visit for owner reassurance
• Know the location and hours of the nearest exotics veterinarian
• Communicate proactively with the owner about any concerns, however minor they may seem

Caring for reptiles as a pet sitter is a responsibility that demands attention to detail, respect for species specific needs, and a willingness to learn. With proper preparation, a clear care plan, and open communication between owner and sitter, bearded dragons, leopard geckos, and corn snakes can thrive while their owners are away.
