First time snake owner.

Morning. I just brought home my first snake home yesterday. He is a beautiful young pastel male. I had some branches in my tank for it to climb on, but after looking into it I found out that they were two pieces of old cedar. I know cedar is toxic to reptiles so when I realized my mistake I removed the branches immediately. My lil guy was exposed to it for about 6 hours. I'm wondering if I caused any irreparable harm?

It's fine. The major problems come from the dust it creates with bedding. Six hours in stick form isn't a big deal.

Welcome to the forum.

Glad you caught the mistake. Look forward to seeing some pics! :)
