Yeah the gurgling was the first time I've ever heard it. He was cruising all over me though and standing up trying to reach the ceiling and stretching out. My boas make that gurgling from their gut sometimes too. Usually it is a prelude to a big turd lol.
And yeah, I guess 200g would be a small large. My gal sells mediums up to about 170-180g. Then her larges are about 190g-280g.
