Yep. Extruder 1 for the main body and extruder 2 for the smaller parts (Ears, tail, feet and chest parts).
I used merge to merge the two sets of objects together. It's weird because when I turn on the second extruder with both objects ungrouped, it cuts off at the ears:
I did edit the ears in the model not too long ago to see if it was the size of the object, but same thing happens.
