Boa constrictors are impressive but demanding pets whose welfare requirements scale with their size over their 20-30 year lifespan.
Adult boa constrictors in inadequate enclosures suffer from scale rot from insufficient humidity, respiratory infections from cold temperatures, and obesity or malnutrition from incorrect feeding schedules. Owners who acquire an 18-inch hatchling often have not considered the 9-foot adult the animal will become. Surrendered boas frequently have health problems from years of inadequate care.
