Sorry, I shouldn't have started that ball rolling here
More focused on the topic, my wife mentioned our snakes in her office environment and it turned out her coworker had an extensive herp collection, including venomous. Their talking about snakes has drawn in other coworkers in a positive way. The comfort level was raised so much that her coworker actually brought in a ball python to integrate in a therapy unit one week.
So sometimes just sending out feelers and then general conversation is able to increase the comfort level of people without needing an overt display.
