Whats the average lifespan for a WHS

I've had my hoggie for going on 12 years now, and was wondering what the average is. I have read a few different caresheets that said different things. So I figured I would come ask on here. I am hoping she has alot more years. My mom was deathly afraid of snakes when she bought her for me when i was 16 and now she absolutely loves her. No if i can only get her to come around with my new Bp lol She wont go anywhere near the qt room when she comes over to visit.:rofl:

If properly cared for a hognose snake can live as long as 25 years give or take...

Thank you. Hopefully she will be here when shes 25 or more.
