I have noticed something about my 2 iguana's.Yoda the one I recently built the enclosure for.Her mouth and tongue is a dark shade of pink.Then Grinch who is not yet in his enclosure.His mouth and tongue are a light pink color.Any idea's on why this is?is there cause for any type of concern?I read that just means they are healthy.I would post a picture but I dont think they would like me trying to take pictures of the inside of their mouth's.Maybe i'm just overly concerned,but I guestion everything that changes with them.After all they are part of the family
