It looks like your Animal class is abstract and should never be constructed. Declare Animal 'abstract' and see if you get an instantiation error.
Have your tried to put the 'public static final Parcelable.Creator CREATOR<Cat>' and 'public static final Parcelable.Creator CREATOR<Dog>' variables and definitions in both Cat and Dog (and not in Animal)? This will make sure that the factory-method createFromParcel creates the appropriate subclass (Cat or Dog, and not Animal). About the readFromParcel(). If Cat and Dog both implement readFromParcel() it should work fine. Are you sure that the variable 'a' is not an Animal instance?
