My Savannah monitor just finished another shed about 9 or 10 days ago, and returned to his beautiful dark grey self. I went to change his water and give him a snack today, and I noticed he's back to the pale brown color he get's when he's shedding and I dont know why? He's still very alert,energetic,and his appetite is HUGE as always. He appears healthy, but his colors have changed. I can't finda ny information about this online....has anybody ever encountered this before?
