So since some of you know I have a feeding issue with my BP Spaz. With rat pups they dont' move around so much so I noticed they go up to them, smell them, poke them with their noses, then move up to the head/neck then bite/coil.... No since i tried to use a live mouse with Spaz he tried to do the same thing until the mouse ran, then he got into a defensive ball. How did you all make the switch... did it happen naturally or did you have to use a fresh killed mouse/rat?
