Picked up my Hog Island from the LPS where I work part time. Most of the time he looks really light like this:



The day I go to see him and show my hubby, he was really dark with heavier speckles. I go back later that night to buy him and he was lighter but not like above. After a few hours home, I got him out to do some exploring, and he lightend again:



Tonight, I go to see him and he's dark again, but seemed to lighten slightly while he was out. I don't mind the color changes, it's really interesting. However, I was wondering why? Is it linked to moods, temps, or comfort levels? He had eaten thurs am and I picked him up late friday pm. Could it be extra camo to hide while digesting?
