Veiled Chameleon

Overview

Veiled chameleons are among the hardiest chameleons available ². They are still an observation pet rather than a cuddly one. Most tolerate handling poorly, and many are given up because their husbandry is more demanding than new owners expect ². Males are larger and brighter, reaching 18 to 24 inches, while females reach about 14 inches ³. Females typically live three to five years and males four to six, with some living to six or seven ³.

Natural history

Veileds come from Yemen and southwestern Saudi Arabia, in environments from dry plateaus and grassland to seasonal desert streams and coastal plains ¹³⁴. They are solitary, slow-moving, and live in trees and shrubs ¹².

Like all chameleons, they are built for life in branches ²³⁴:

• Their eyes swivel independently.
• Their tongue extends to about two and a half times the body length.
• Their tails and mitten-like feet grip branches.

Color changes signal mood, temperature and health. Persistently dark coloring can be a sign of stress or illness ²⁴. Escaped veileds have become invasive in Hawaii ².

Enclosure

• Screen, not glass. A tall, well-ventilated screen enclosure ¹².
• Size. At least 2 ft × 2 ft × 3 ft tall for an adult, and much larger is better ²³.
• Alone. Keep each chameleon by itself. Constant sight of another male can stress a male into illness, and reflections in glass can cause the same problem ¹².
• Climbing. Many branches of different diameters, with slightly springy vines to rest the feet. Avoid cotton rope perches, whose fibers can strangle toes ².
• Plants. Dense live plants such as pothos, ficus or umbrella trees for security and drinking droplets. Ficus sap can irritate, so prune the plant outside the enclosure ¹².

Temperature & lighting

Use a heat lamp on a thermostat, and keep branches far enough from the bulb that the chameleon cannot burn its casque or back ¹². Run a 10 to 12 hour photoperiod. Lights left on constantly cause stress ².

UVB is essential for calcium absorption ¹²:

• Window light does not count.
• Dense screen can block up to half the UVB.
• With a fluorescent tube, the chameleon should be able to get within 12 to 18 inches ¹.
• Juveniles and sick chameleons need a stronger 10.0 bulb ².
• Replace UVB bulbs every 6 to 12 months ¹².

Humidity

Daytime humidity of about 30 to 60% with good airflow suits veileds ¹²³. Let it rise at night, up to 75–90%, because they absorb much of their water from humid air ².

Most chameleons will not drink standing water. Mist several times a day, or use an automatic mister or drip system aimed so droplets form on leaves, and give hatchlings droplets at least twice a day ¹². Clean misters and drippers weekly. Contaminated water and low humidity are linked to eye infections and gout ².

Substrate

Bare floor, newspaper, butcher paper or indoor/outdoor carpet is easiest. Loose substrate can be swallowed with prey ².

Diet & supplementation

Veileds mostly eat insects, with the odd nibble of plants ¹².

• Insects. Feed a variety: crickets, roaches, silkworms, hornworms, soldier fly larvae and some worms, no larger than the space between the eyes ¹².
• Gut-loading. Gut-load feeders for 24 hours with calcium-rich greens and vitamin A–rich vegetables ².
• Cup feeding. Feeding from a cup lets you see what is eaten. Never feed against glass or plastic: a tongue strike on a hard wall can cause permanent injury ².
• Greens. Some veileds eat collard or mustard greens, romaine or hibiscus a few times a week ²³.
• How often. Most chameleons eat daily, and larger adults every other day. They overeat readily ².
• Supplements. Dust insects with a phosphorus-free calcium ¹²⁵. Tree of Life Exotic Pet Medical Center recommends calcium without D3 daily plus a multivitamin containing true vitamin A once or twice a week ¹. Ask your vet to tailor this.

Handling & temperament

Approach slowly. Slide your fingers under the front feet, unwind the tail gently, and let the chameleon step on. Never pull it off a branch ². Chameleons cannot drop and regrow their tails, so a tail injury is permanent ². Wash your hands after contact, as reptiles can carry Salmonella ⁸.

Health

Common issues ²⁴⁵

• Metabolic bone disease. Rubbery jaws and limbs, and fractures without trauma.
• Egg retention in females (see below).
• Gout and kidney disease, linked to phosphorus-containing supplements and low humidity.
• Eye-turret swelling and vitamin A deficiency.
• Mouth rot, respiratory infections, parasites.
• Burns from lamps, and foot sores from poor perches.

When to see a vet

See an exotic-animal vet for persistently dark color, closed or swollen eyes, weakness, appetite loss or a swollen belly that does not resolve ⁴⁵. Weakness, a female who is thin and swollen with eggs, or a limb with extra bends are urgent ⁵.

Breeding overview

Female veileds can lay 20 to 70 eggs per clutch ⁵⁶. She needs enough calcium, correct temperatures and a place to dig a nest, or she may be unable to lay (egg retention) ⁵. Veileds are sexually mature at four to eight months ³. Males have a taller casque and a heel spur (tarsal spur) that is visible from birth, which makes sexing easy ¹³.

Legal & ethics

Chamaeleo calyptratus is listed on CITES Appendix II ⁷. Pet veileds may be captive bred or wild-caught imports ³, so choose captive-bred. Never release a chameleon: escaped veileds are invasive in Hawaii ².
