Snakes kept as pets have complex environmental and behavioral needs that are frequently misunderstood, leading to chronic stress and shortened lifespans.
Snake welfare in captivity is severely compromised by fundamental misunderstandings of their needs. Many snakes are kept in enclosures far smaller than they need - a common rule of thumb that enclosure perimeter should equal the snake's length is woefully inadequate. Snakes in the wild may travel miles, and completely restricting this movement causes chronic stress. Inadequate temperature gradients prevent proper digestion and immune function. Social isolation is appropriate for most species, but the psychological needs of snakes for environmental complexity, hiding places, and ability to thermoregulate remain important. Wild-caught snakes in the pet trade suffer severely from collection stress and often die within a year of capture. Captive-bred snakes from responsible breeders fare better but still require extensive care.
