Thanks guys!
Has he grown? Oh yeah. He will have been with us for a year next month and in that time, he's grown @8lbs (currently at 35lbs) and about 10" (currently at @10.5' - he's hard to measure accurately). He has only denied eating twice in that time, mostly at 1-2 jumbo rats a week, but we're moving him to a large item (3-5lb rabbit or pig, depending on availability) once a month.
His age when we got him was only roughly known as 4 to 5 years, so I'm calling him 5 years old now since it's been a year.
I'll try to get more regular posting pictures of him; it's a bit tough since he's always on the move when he's out of his enclosure, so it's difficult to photograph him even with 2 people, hehe!
