A few days ago i fed my savannah monitor, a little more than usual. Normally i feed her a single mouse, this time i fed her a single mouse and a hopper, she had no problem eating them. I tried offering her a few crickets last night and she would have nothing to do w/ them. THen i tried a hopper today, and she didnt want that either. I changed a few things in her cage a couple days prior to feeding her, could this have anything to do w/ it?? her temps are good, and her poop is firm not runny at all, any ideas???
