Group Guide
Reptiles
Quiet, exact and startlingly long-lived — the group where the checklist matters more than the cuddle.
A reptile outsources its body temperature to you. Heat, light and diet are not comforts here — they are the animal’s physiology, run from the wall socket — and kept exactly, reptiles are calm, quiet companions on timescales that embarrass most pets. One thing comes before any of it: reptile keeping is licensed and restricted differently almost everywhere, including state by state within Australia, so the first thing to acquire is knowledge of your local rules — not an animal.
At a glance — all reptiles

Most of what goes wrong for pet reptiles is husbandry before it is disease — and treatment does not succeed unless the environment is corrected too.1 The checklist is the keeping.

The three things that kill pet reptiles
- Wrong heat. An ectotherm in a cold enclosure cannot digest, heal or defend itself — and an overheated one can die faster still.
- Missing UVB and calcium. The most common bone disease in pet reptiles is a lighting and diet failure, not bad luck.
- The impulse buy. A cheap animal with exact needs, a licence requirement and a multi-decade lifespan is the opposite of a starter pet.

- Disorders and Diseases of Reptiles. MSD Veterinary Manual 2026. Accessed 2026-09-05. International MSD Veterinary Manual Secondary nutritional hyperparathyroidism — metabolic bone disease — is the most common bone disease seen in pet reptiles, driven by poor calcium-to-phosphorus ratios, insufficient vitamin D3, lack of UVB light and inadequate temperature, and it predominantly affects rapidly growing plant- and insect-eating lizards, turtles and tortoises. Respiratory infections including pneumonia are common in reptiles and are tied to unfavourable temperatures, poor sanitation and malnutrition. Treatment does not succeed unless nutrition, environment and sanitation are corrected too.
