Hm, just wondering...but is anyone concerned about their snake picking up a fatal disease in a petshop ??
Surely, if a snake is taken along to a petshop that sells reptiles, it will be admired and probably touched by employees. The employees that handle the other reptiles in the petshop. Who gets their reptiles from all kinds of sources and there may very well be some that could have infectious diseases. IBD comes to mind.
It would be heartbreaking to me to loose a snake, or worse my whole collection, due to taking risks like that. After talking to someone who lost his entire collection and went through a lot of heartbreak, I can see why many people keep a "closed" collection and have very strict quarantine in place...
Also, I don't take my snakes to places where they come close to other people that may have a snake phobia. I did take them to educational shows and planned events, though.
