I wonder about all those animals myself. I'm 31 and it's fairly common for visitors my age or younger to tell me they "had" a snake or an iguana like mine, some died, some were rehomed. The only person I know that's held onto a snake for a few years I'm taking care of it currently and it's your typical pet setup-big fish tank, human heat mat, no heat regulation, massively overhandled and 500 gram @ 5 year old bp so rather miraculous he's made it this long. I doubt most do from what I've seen personally and around forums. It's why I buy from breeders who care about their animals and don't just breed anything and everything to make a buck. In case anything happens to me most of my snakes will return to their breeders, some have another owner lined up and a couple could stay with my husband or nephews if they choose.
