Re: Speech Topic
The history of them as pets in north america would be fun, or maybe something on anatomy (quills, muscle system for quills, etc). Not sure... I'm always hesitant to mention them, especially in front of large quantities of stupid people (LOL), so I'd steer away of too much on care unless you emphasize the expenses, heating, vet bills, in general make them sound very high maintenance to ward off impulse people.
If you do want info on history you can PM me, I've talked to several people who were around or have talked to people that were around during importation and the beginning of them as pets here. There isn't a ton of info but I can help you with what I have.
