Your iguana can't tell you the UVB has faded or that too much protein is straining its kidneys. baskr watches the pattern across your logs, temperature, humidity, weight and feeding, and shows you what needs attention before it becomes a problem.

Tube is over 12 months old and growth has slowed. Replace it before MBD sets in.
Basking spot

Adult size

Ideal ranges for Iguana iguana, the same targets baskr scores your logs against.
Basking and warm figures are surface temperatures at the spot; cool and ambient are air. Measure with a probe or infrared thermometer at the animal's height.
Diurnal
Active by day
Rainforests of Central & South America
Wild climate. Warm, humid tropical rainforest and riverbanks; hot, bright and humid, high in the canopy.
Why the care is what it is. This is why baskr targets a 35 to 40°C basking spot, strong wide UVB, 70%+ humidity, a strictly herbivore diet and a huge arboreal enclosure.
Logging is the input. The product is spotting when a single off reading becomes a pattern worth acting on.
35–40°C (95–104°F) at a sturdy basking branch
A cool basking spot undercuts digestion in a large herbivore.
Strong, wide UVB across the basking zone, renewed yearly
Weak or faded UVB is the fast track to metabolic bone disease in a fast-growing lizard.
70%+ for a rainforest species
Chronic dryness causes poor sheds and dehydration; support kidney health with good hydration.
Leafy greens and vegetables, calcium-dusted, no animal protein
Protein (insects, dog food, meat) damages iguana kidneys, keep it strictly plant-based.
Steady, smooth growth
Poor growth or a thin tail base points to husbandry or UVB problems.
Room to climb, with height and branches
A cramped, too-small enclosure stresses an iguana and can drive aggression.
Safe to include
Avoid
Think salad garden, not feeder insects: a varied, calcium-rich plant diet is the whole basis of iguana health.
Staples
Occasional / treats
Never feed
Supplements. Calcium (with D3 if UVB is marginal) at most feeds, plus a multivitamin occasionally, bone health is a constant priority.
Good to know. A strict herbivore. The single most important rule: greens and vegetables, never animal protein, which damages iguana kidneys.
The right kind of kit, pick brands you trust.
UVB lighting
Strong, wide 10–12% T5 HO coverage (Ferguson zone 3–4) over the basking zone, replaced every 12 months.
Basking heat
A basking setup to reach 35–40°C at a sturdy branch, on a thermostat.
Thermostat
Controls the heat safely across a large enclosure.
Thermometer + hygrometer
To hold the hot basking spot and 70%+ humidity.
Custom enclosure
The defining cost: a room-sized, tall, custom-built arboreal enclosure for the adult.
Large water / soak area
A big water area to soak, supporting hydration and healthy sheds.
Grounded in your own logs and the ideal ranges above, plain language, never a diagnosis.
UVB tube is over 12 months old and growth has slowed. Replace it, faded UVB is the classic cause of metabolic bone disease in iguanas.
Animal protein logged this week. Iguanas are strict herbivores, protein strains their kidneys, keep the diet fully plant-based.
Basking spot averaged 31°C, below the 35–40°C this large herbivore needs to digest. Check the lamp and branch height.
Very big: 1.5–2 m (5–6 ft) including the tail, and heavy-bodied. They need a custom, room-sized enclosure as adults, which is why so many are rehomed. Be sure you can house a full-grown one for 15–20 years.
They're strict herbivores: leafy greens and vegetables, calcium-dusted. Never feed animal protein (insects, meat, dog food), it damages their kidneys. This is the most important iguana rule.
No. Between the eventual size, the strict diet, the strong UVB and humidity needs, and breeding-season aggression in males, they're a demanding, advanced, long-term commitment.
Yes, strong, wide UVB is essential. They're fast-growing basking herbivores, and without good UVB (and calcium) they quickly develop metabolic bone disease.
