ok i fed rex his 1st rat around 3wks ago. ever since he wont eat, anything, not even a mouse. i think its becaue of the transition from mouse to rat. well i tryed the rub the mouse on rat thing, no luck, just made the rat stink worse like rat, and the mouse stink lik rat. so tonight, im gonna feed him a weanling mouse, then after im gonna try the small rat. any other tips if this dont work?
