Looks how to spot one
Smooth scales; heavy-bodied constrictor
A powerful, thick-bodied snake with an arrow-shaped head marked by three stripes. The cream, grey or brown body carries darker saddles that turn richer and redder towards the tail, which is where the name red-tailed boa comes from.12
Personality what they are like
The boas most often kept as pets are known for a steady, placid temperament and usually become very tame with regular handling. They are mainly active at night and around dusk.312
Daily activity how busy a day looks
Semi-arboreal: moves well on the ground and also likes to climb, so the enclosure needs floor space to stretch out plus sturdy branches for climbing.24
Grooming and care the hands-on bits
Raise humidity to around 75-85% during sheds and offer a humid hide lined with damp sphagnum moss on the cool side. Prefer frozen-thawed prey over live.56
Home where they are happiest
Enclosure roughly snake length x half length x half length. Typical adult (1.8-2.4 m): at least 180 x 90 x 90 cm; larger adults about 240 x 120 x 120 cm. Basking area 30-32 °C, cool side 24-26 °C, night down to about 20 °C. Humidity 55-75%.475
Food basics what goes in the bowl
Whole prey such as rats, mice, young rabbits and birds (chicks, quail). Meals should be no more than about 10% of the boa's weight or no wider than its widest point. Young boas eat every 10-12 days; adults over 4 years every 4-8 weeks.6
Company who they like around
The story where it all began
Linnaeus named the species in 1758, and it remains the only animal people regularly call by its full scientific name in everyday English. It has long been one of the most popular large snakes in the pet trade, and many generations have now been bred in captivity.12

Owner questions the things everyone asks
How often should I feed my Boa Constrictor?
Young boas eat every 10 to 12 days, while adults over 4 years eat every 4 to 8 weeks. Furry Diary's starting plan suggests adjusting frequency based on age and size, so always check your snake's condition.6 Furry Diary plan
What does a Boa Constrictor eat, and what should it never eat?
It eats whole prey like rats, mice, young rabbits, and birds. Never offer prey larger than about 10% of its weight or wider than its widest point, and frozen-thawed prey is preferred over live for safety.65
How much space does a Boa Constrictor need?
An enclosure roughly the snake's length by half that by half that. For a typical adult (1.8, 2.4 m), aim for at least 180 x 90 x 90 cm; larger boas need up to 240 x 120 x 120 cm. Include floor space and sturdy branches for climbing.42
What temperature, light or water does a Boa Constrictor need?
Provide a basking area of 30, 32°C, a cool side of 24, 26°C, and night temperatures around 20°C. Humidity should be 55, 75%, raised to 75, 85% during sheds with a humid hide. Fresh water must be available daily, as in Furry Diary's plan.475 Furry Diary plan
How often should I clean a Boa Constrictor's home?
Spot clean every 2 days and do a full clean once a month, as suggested in Furry Diary's care plan. This keeps the enclosure healthy and your boa comfortable. Furry Diary plan
Can a Boa Constrictor live with others?
No, boas are solitary and must always be housed one per enclosure. They do not need or benefit from company.42
How long does a Boa Constrictor live?
With proper care, a boa constrictor can live 20 to 35 years. This is a long-term commitment, so be prepared for many years of companionship.123
Can I handle a Boa Constrictor?
Yes, they have a steady, placid temperament and usually become very tame with regular handling. Always support their body and handle gently to keep them comfortable.312
