How Long Do Uromastyxs Live?
Uromastyx commonly live 15 to 20 years, with individuals reported near 30, which puts them among the longest-lived lizards kept. Almost everything that shortens that comes from treating them like a generic desert lizard.

|---|---|---|
| Commonly published | 15-20 years | The usual captive range |
| Some individuals | Reported to around 30 years | Records exist |
| Long-lived | Yes | Among the longest-lived pet lizards |

What actually shortens it
Published lifespans describe well-kept animals. The gap between the figure above and what a uromastyx actually lives is almost entirely husbandry, and these are the levers that matter most.
Humidity
The uromastyx-specific killer, and the opposite of most reptile problems. They are extreme desert specialists, and ambient humidity that would suit a bearded dragon causes respiratory infections in them.
Metabolic bone disease
The leading husbandry cause of death in captive lizards, and a lighting failure more often than a diet one. UVB bulbs lose useful output within 6 to 12 months while still looking lit, and glass filters UVB out entirely.
Animal protein in adults
Adults are herbivores. Excess animal protein is associated with gout and renal disease in this genus, and dehydration and over-supplemented D3 compound the risk.
Common questions
How long do uromastyx live?
Commonly 15 to 20 years, with individuals reported near 30. They are among the longest-lived lizards in the hobby.
What shortens a uromastyx's life?
Humidity, which causes respiratory infections in an extreme desert specialist. Excess animal protein in adults is the other, being associated with gout and renal disease in this genus.
Do adult uromastyx need insects?
Adults should not be fed insects. There is no demonstrated benefit, and excess animal protein is associated with gout and renal disease, with dehydration and over-supplemented D3 compounding the risk.
