ActiveAndroid abstract class table

Does anyone know if it is possible to create a table for an abstract class in ActiveAndroid. For example i could have an abstract class Animal with two concrete classes Dog and Cat. I want to be able to do something like:

List<Animal> animals = new Select().from(Animals.class).execute();

which would result in 'animals' containing all of the saved Cats and Dogs. Or:

Animal animal = new Select().from(Animals.class).where("name = ?", name).executeSingle();

Where 'animal' could be either a Cat or a Dog. Unfortunately when I do this I get an exception because no table is created for the abstract class Animal. Does anyone know how I might go about this using ActiveAndroid?
