Sometimes what I do, if my roommates are home and can keep an eye on him, I'll leave Nagini on the coffee table while I run upstairs for something, or do up my dinner dishes. I went back into the family room with dessert and a glass of water and Nagini was nowhere on the table. Seeing my panicked face, my best friend pointed and said "I have kept an eye on him. Have you ever seen him climb down from the coffee table?" Well I hadn't and suffice to say I was more than surprised to see how agile they are at climbing. For a non arboreal species.
