I think our Pixel wants more space. I didn't expect him to grow any more. When we got him we were told he was 2 years old and wouldn't grow any more. But he is getting longer. Don't know why. He needs a bigger home! Big Question: Do they have a preference of being able to see out, as in a terrarium, or is purchasing an enclosed custom cage ok? We work during the day and I thought being able to see and even hear the goings on in the house and or outside would help keep him less bored.
