Well, if not actual shows, maybe fun matches?

Ferret shows have fun matches, were you just show off your fuzzy doing what it does best. There aren't any breed specifications or such, more or less just a way to enjoy your pet and maybe win a ribbon.

That would be easy enough for snakes, I think. You could divide them into species, like balls, red-tail boas, dumerils, etc. And you just bring your best for people to admire.
