Looks how to spot one
scales
A heavy-bodied, terrestrial snake with a grey-brown ground colour and darker, irregular patches. This pattern provides excellent camouflage among leaf litter on the forest floor. The belly is pale.12
Personality what they are like
Dumeril's boas are known for their calm and gentle nature. They rarely bite and tolerate handling well, though they have a strong feeding response so keepers should use tactile cues before handling. They can be stressed by over-handling, so interaction should be moderate.534
Daily activity how busy a day looks
Low activity needs. They are primarily nocturnal and spend most of their time on the ground. They do not require climbing space. A large, floor-based enclosure with hides and a water bowl is sufficient.53
Grooming and care the hands-on bits
Minimal grooming. Provide a large, sturdy water bowl for drinking and occasional soaking. Misting in the morning can help with humidity spikes, especially during shedding. Clean the enclosure regularly.53
Home where they are happiest
A terrestrial enclosure with a floor space of at least 6 by 2 feet for an adult. Daytime temperatures in the mid to upper 80s °F (about 30-32 °C) with a basking spot, dropping 10 °F at night. Low UVB requirements (Zone 2 HO-T5). Provide leaf litter, hides, and a water bowl. They are not venomous and not illegal to keep in most countries, but check local regulations.53
Food basics what goes in the bowl
Carnivorous. Feed appropriately sized rodents (mice for juveniles, rats for adults) every 7 days for young snakes, every 10-14 days for adults. Prey should leave a noticeable lump. In the wild they eat birds, lizards, small mammals, and even other snakes.31
Company who they like around
Solitary. They do not require company and should be housed alone. Handling should be done gently and not excessively to avoid stress. Not venomous; legal to keep in most places but check local laws.35
The story where it all began
Dumeril's boas were once exported from Madagascar in large numbers for the exotic pet trade. Today, exports are heavily restricted, but the species breeds well in captivity, so captive-bred individuals are widely available. They have become popular as pets due to their docile nature and manageable size, though they are best suited to keepers with some experience with large constrictors.15

Owner questions the things everyone asks
How often should I feed my Dumeril's Boa?
