# Keeping boa constrictors: profile and care

## For experienced keepers – size, climate and feeding

### At a glance

- **Adult size:** 120 to over 300 cm depending on subspecies (males usually smaller)
- **Origin:** Central and South America
- **Suitable for beginners:** no – their size means experience is required
- **Lifespan:** 20–30 years

### The right vivarium

At least 180 x 80 x 80 cm for adults, and larger for bigger specimens. With a robust substrate such as bark chippings, sturdy climbing branches, hides and a water container large enough to bathe in.

### Temperature, lighting & climate

- Daytime 28–32 °C, basking spot up to 35 °C
- Night-time 22–25 °C
- Humidity around 60–75 %, slightly higher for some subspecies
- Heat lamp, UVB lighting and a thermostat-controlled heat mat

### Feeding

Frozen-thawed food such as rats or rabbits: juveniles every 10–14 days, adults roughly every 3–4 weeks. Avoid overfeeding, as boas put on weight easily.

### Temperament & handling

A calm temperament, active around dusk and at night, and generally not aggressive. Powerful nonetheless, so handle with respect – not an animal for children.

Because of their size, boa constrictors are not suitable for beginners.
