The veiled chameleon, from the Arabian Peninsula, is a large, casque-headed arboreal lizard with independently moving eyes, a projectile tongue and colour-changing skin.
It is one of the hardier chameleons but is still a specialist animal, not a beginner pet despite being widely sold as one.
Chameleons are easily stressed, intolerant of mistakes in heat, light, hydration and ventilation, and have relatively short lives, with breeding females often shorter still.
They do not tolerate handling well.
A veiled chameleon rewards a meticulous, attentive keeper but quickly declines under casual or under-researched care.
Housing
House one chameleon alone in a tall, well-ventilated screen or mesh enclosure of at least 60x60x120 cm, densely planted with live foliage and a network of branches and vines for climbing and security.
Vertical space, cover and airflow matter more than floor area, and glass tanks tend to trap stale, humid air.
Provide a basking spot of about 29-33C at the top under a heat lamp, cooling lower down, plus a UVB source, as chameleons are very prone to metabolic bone disease.
They rarely drink from bowls, so hydration comes from misting several times daily and ideally a dripper; allow the cage to dry between mistings.
Diet
Veiled chameleons are primarily insectivores that take a varied rotation of gut-loaded live insects such as crickets, locusts, dubia roaches and black soldier fly larvae, with fatty insects like waxworms as rare treats.
Variety and proper gut-loading are essential for nutrition.
Dust insects with calcium at most feedings and with a vitamin/D3 supplement on a careful schedule, as both deficiency and excess cause harm.
Unusually for chameleons, veileds nibble some plant matter, so use only non-toxic live plants.
Hydration through frequent misting is as important as food; dehydration and metabolic bone disease are leading killers.
Health
A healthy veiled chameleon has bright, alert eyes, a firm grip, good colour and steady weight.
Metabolic bone disease from poor UVB or calcium, dehydration and kidney problems from inadequate misting, and stress-related decline are the dominant causes of illness, alongside mouth and respiratory infections from incorrect conditions.
Females mature young and can produce infertile eggs whether or not they have mated; without a proper egg-laying site they risk fatal egg-binding, which contributes to their shorter lifespan.
Sunken eyes, dark stress colouration, lethargy or swollen limbs warrant a prompt visit to an experienced exotics vet.
Temperament
Veiled chameleons are visual, solitary, easily stressed animals that view handling and even close observation as a threat.
They signal stress through colour and posture, and forced interaction causes real harm, so they are display animals rather than pets to hold.
They must be housed strictly alone.
They are highly territorial, and the sight of another chameleon, including a reflection, causes chronic stress; cohabiting leads to aggression, intimidation and decline.
Even visual contact between separate cages should be avoided.
One chameleon, one private enclosure, is the only correct setup.
A good fit for
Experienced, detail-oriented reptile keepers
People who want a striking display animal
Keepers who can mist and monitor daily
Those who accept a hands-off, no-handling pet
Common mistakes to avoid
Buying as an 'easy' beginner reptile
Dehydration from too little misting
Skimping on UVB, causing metabolic bone disease
Any cohabiting or visual contact with another chameleon
Chameleons decline quietly and are usually presented late. Watch the eyes and the grip.
Go now
Sunken eye turrets, or eyes kept closed during the dayGo now. Dehydration and infection both present this way, and a chameleon with closed daytime eyes is already unwell.
Now
Weak grip, falling from branches, or resting on the floorGo now. An arboreal animal on the floor is a serious sign.

Today
Dark, dull colouring held for daysCheck temperatures and hydration, then call. Colour is a stress and thermoregulation readout, not just mood.
Today
Chameleons need no visual contact with other chameleons. Even seeing one another through glass is a chronic stressor.
This is general guidance for a healthy adult, not a diagnosis. An exotics vet who knows your animal always overrides it — and the time to find one is before you need one.
Can a veiled chameleon eat that?
Reptile diets split hard by species. An insectivore and a grazing tortoise share almost nothing, so check the species guide as well as this list.
Never (15)
AlcoholNo safe amount at any body weight on this site.

AvocadoPersin. Fatal to many reptiles.

CaffeineCoffee, tea and energy drinks. Cardiac and neurological toxicity at tiny doses for an animal this size.

Rare treats (1)
WaxwormsVery fatty. Useful for a underweight animal or for medicating, addictive otherwise. One or two, rarely.

Occasional (5)
Bell pepperSafe, low oxalate, and the colour gets a refuser eating. A few small pieces a few times a week.

Butternut squashWell tolerated and a useful source of vitamin A precursors. Small cubes a few times a week.

KaleGood calcium, mild goitrogen. Rotate it. Twice a week.

MealwormsHard chitin shell and a poor calcium ratio. Fine as part of a varied feed, poor as the whole diet. A few, alongside better feeders.
occasional
SpinachOxalates bind dietary calcium, which is the last thing a reptile at risk of metabolic bone disease needs. A very small amount, rarely.

Everyday foods (6)
Black soldier fly larvaeUnusually high in calcium; one of the few feeders that does not need dusting. Several per feed.
everyday food
Collard greensOne of the best staple greens for herbivorous and omnivorous reptiles. Daily.

CricketsA standard feeder. Gut-load them for 24 hours before offering, or you are feeding an empty shell. Sized no wider than the space between the animal's eyes.
everyday food
Dandelion greensExcellent calcium-to-phosphorus ratio and readily taken. Pick away from sprayed ground. Daily, for herbivorous species.
everyday food
Dubia roachesBetter calcium ratio and more meat per insect than crickets, and they cannot climb glass. Sized to the animal.
everyday food
Mustard greensGood calcium ratio; rotate with other greens. Several times a week.
everyday food
That food is not on our list. Reptile diets are narrower than they look — check the species guide, and ask an exotics vet before offering anything unfamiliar.
Dust feeders with a calcium supplement to the schedule in the species guide. A reptile can be eating well and still be starving of calcium.
