Yes you are correct Rachel. The term agoraphobia is often misused and assumed to mean someone or something is afraid of open space. In reality, agoraphobia, as it applies to the human condition, is usually associated with panic disorder...people who suffer from panic attacks are afraid to leave home (or an area that they know) because they might have a panic attack outside their "saftey zone," and be embarrassed because of it. True agoraphobia all by itself is very very very rare and usually involves many other mental issues. Thus this term doesn't really apply to small snakes in large vivs...the stress that they seem to suffer from being in a large tank is most definitly a vulnerablity/saftey issue rather than "agoraphobia." Therefore, providing them with lots of places to hide should take care of this problem, I would assume (speaking only logically of course.) If this were not true then every snake born in the wild would certainly go insane seeing how the outdoors is much much bigger than any large tank somebody could build or buy. Sorry to go scientific on everyone...just wanted to clear up the definition problem since I see many people on this board use it incorrectly.
Thanks.
