Well, how would I declare std::vector? std::vector<what>? Using boost::any will require me to do some sort of type discovery at run time. Thanks for pointing the boost::variant to me; that will work. What would be a _proper_ way to design a templated class so it can be stored in a (boost) container?

std::vector< boost::variant > v;

Or instead of Boost.Any, create a base class for it all called like AnimalBase that is non-templated, then your above templated Animal class will be as it is, but subclasses from Animal, then put abstract calls or whatever similar functionality in AnimalBase to link it all. Variant is faster all around if you know all of your types before hand.
