I recently found a king rat snake (extremely beautiful/ sort of looks like a king cobra with faded white lines and solid dark grey body) in my area, comes with cage and everything, the seller was offering me everything for FREE! I wanted to know if I should take that deal or not because I don't really know much about the species and it seems to be really uncommon in the pet trade, I keep large constrictors like burms and retics so I'd like to think of myself as experienced but I'm not really familiar with this species of snake. Should I take the deal? Thoughts? Worth it?
