Environmental Control: UVB, Temperature/Humidity Gradients, and Ventilation

Chameleons are extremely sensitive to light and their environment. A UVB light source is used to synthesize vitamin D3, which helps with calcium absorption. Light tubes should be replaced regularly according to the manufacturer’s recommendations. The cage should be set up with a temperature gradient (the daytime range and basking spot are warmer, with a moderate drop at night). Use a misting or drip system to maintain humidity, but ensure high ventilation to prevent mold. The enclosure should be placed indoors, away from air conditioner vents and direct sunlight. During Hong Kong’s humid season, pay attention to musty odors and excessive water buildup.

Diet and Nutrition: Live Food, Calcium, and Vitamin D3 Supplements

The main diet for chameleons is live insects (crickets, dubia roaches, etc.). Gut-loading and dusting the insects with calcium powder and a multivitamin are key. Young chameleons need more frequent calcium supplementation, while the frequency for adults can be adjusted based on a vet’s advice. Avoid overly fatty food (like mealworms) to prevent obesity or a burden on the liver. Chameleons primarily drink from water droplets on leaves, so daily misting is necessary.

Common Health Warnings and When to Seek Medical Attention

Refusing to eat, weight loss, a soft jaw or weak limbs (suspected metabolic bone disease), stuck shedding, open-mouth breathing or wheezing, and sunken or closed eyes are all common warning signs. If any of these symptoms appear, schedule an appointment with a reptile vet as soon as possible.

Reptile Clinic Process and Examination Items

A clinic visit typically includes asking about the environment and light exposure history, and a physical examination. If necessary, a fecal test for parasites, blood biochemistry, X-rays, and ultrasound imaging will be done. Some cases may require short-acting sedation or gas anesthesia to safely complete imaging or procedures. Owners should bring recent weekly environmental data (temperature/humidity, light model, and replacement date) and a fecal sample.

Treatment Direction

Treatment depends on the cause of the illness. Common treatments include: calcium and UVB correction, antibiotics/nebulizer support, fluid therapy and nutritional support, and surgical procedures (such as for egg stasis).

Home Care and Prevention

  • Replace the UVB light on time and maintain the correct basking distance.
  • Establish a day/night temperature and humidity cycle with good ventilation.
  • Provide a variety of live food and supplement calcium regularly; provide water daily.
  • Regularly weigh your chameleon and record its food intake and waste.
  • Have a health check every 6–12 months for early detection and treatment.

Frequently Asked Questions (FAQ)

  • How big of a cage does a chameleon need?
    It needs vertical space, climbing branches, and multiple layers of leaves. The size depends on the species and body size; the larger the cage, the more stable the environment.
  • How often should I change the UVB light?
    Follow the brand’s recommendations (usually 6–12 months) and maintain a suitable distance and clear mesh for light transmission.
  • What should I do if it’s not drinking water?
    Make sure there are water droplets on the leaves and the misting frequency is sufficient. Observe its waste. If it continues to refuse water, seek medical attention.
  • What should I do about stuck shedding?
    Increase humidity and gently mist. Do not forcefully pull at the skin; if it is severe, seek medical attention.
  • Can metabolic bone disease heal on its own?
    Adjust UVB and calcium supplements, and seek medical support when needed. The earlier it is treated, the better.
