YEMEN CHAMELEON

Quick Care Guide

Scientific Name: Chamaeleo calyptratus
Adult Size: 35–60 cm, including the tail
Lifespan: Males 6–8 years; females 4–6 years
Activity: Diurnal • Arboreal

📏 Size

• Males are generally larger than females and develop a prominent casque on the head.

• Requires a tall enclosure with plenty of climbing space.

🏠 Housing

• Adult minimum: 60 × 60 × 120 cm, with larger preferred.

• A tall, well-ventilated enclosure with mesh sides is ideal.

• Provide sturdy branches at different heights and plenty of safe live or artificial foliage.

• Ensure the chameleon can hide completely from view.

• House individually to prevent stress and territorial aggression.

• Avoid loose substrate that could be accidentally swallowed.

🌡️ Temperature

• Basking spot: 32–35°C.

• Daytime ambient: 24–28°C.

• Cool area: 22–25°C.

• Night: ideally 13–20°C, depending on age and conditions.

• Use thermostatically controlled heating and guard heat bulbs against burns.

💡 Lighting

• Provide high-quality UVB lighting, essential for calcium absorption and healthy bones.

• Aim for a basking UV Index around 3, with shaded areas available.

• A suitable linear T5 UVB lamp is recommended; select its strength and distance according to the enclosure and manufacturer's guidance.

• Provide approximately 10–12 hours of daylight daily.

• Replace UVB lamps according to the manufacturer's schedule.

💧 Humidity

• Aim for around 30–50% during the day, with higher humidity overnight where suitable ventilation is maintained.

• Mist foliage to create drinking droplets, then allow surfaces to dry.

• Good airflow is essential to prevent stagnant, damp conditions.

• Monitor humidity using a hygrometer.

🍽️ Food

• Feed a varied diet of gut-loaded live insects, including crickets, locusts, roaches and suitable worms.

• Juveniles generally need daily feeding; adults usually eat every other day or around 3–4 times weekly.

• Offer safe leafy greens occasionally, as this species may nibble vegetation.

• Dust insects with calcium and provide a suitable multivitamin/D3 supplement according to an appropriate schedule.

• Avoid oversized prey and remove uneaten insects.

💧 Water

• Yemen chameleons usually drink droplets from leaves rather than standing water.

• Use regular misting and/or a dripper system to provide moving water.

• Ensure the animal can access droplets safely.

• Clean the dripper reservoir and any water dish regularly.

🐍 Shedding

• Young chameleons shed frequently as they grow; adults shed less often.

• Maintain suitable hydration and provide branches for rubbing against.

• Never pull retained skin off forcibly.

• Seek veterinary advice if shed constricts toes or the tail.

🤲 Handling

• Minimise handling; this species can become stressed easily.

• Allow the chameleon to approach your hand voluntarily where possible.

• Never grab it by the tail or limbs.

• Avoid handling during settling-in, illness or shedding.

❤️ Health

• Healthy chameleons should have alert eyes, a good body condition and a strong grip.

• Watch for sunken eyes, weakness, poor appetite, swollen joints, tremors or difficulty climbing.

• Correct UVB, calcium, hydration and temperatures help prevent metabolic bone disease.

• Arrange veterinary care promptly if breathing difficulties or persistent weakness occur.

🧹 Cleaning

• Remove faeces and uneaten insects daily.

• Clean drinking and misting equipment regularly.

• Disinfect surfaces and furnishings when needed using reptile-safe products.

• Keep ventilation openings clear and allow surfaces to dry between misting sessions.

✅ Before You Bring Your Animal Home

☐ Tall, secure and well-ventilated enclosure ready
☐ Branches and dense foliage installed
☐ Basking and cool temperatures checked
☐ UVB lighting correctly positioned
☐ Misting or dripper system ready
☐ Live feeder insects and supplements available
☐ Heat bulb safely guarded
☐ Reptile-experienced vet identified

⚠️ Important Bits

• Yemen chameleons are arboreal and need height, privacy and excellent ventilation.

• They are best suited to keepers prepared for specialist care.

• Never house two adults together.

• Monitor temperatures carefully to prevent overheating.

• Reliable access to drinking droplets is essential.

• Never use pesticides or chemical sprays near the enclosure.

• Females may lay infertile eggs even without a male and can require suitable laying facilities.
