I have a steppe runner that I got in July. I love him but his tank is small (10gallon). He is the first reptile I have ever owned. He is sweet but whenever I hold him he runs up my arm out of the tank and tries to run around the house which wouldn't be a problem for me if there were't so many places for him to hide and a dog that likes eying him up. I want to create him a place outside his tank that he can runaround and be safe in like a pen or something. Any ideas? Thank you!
