I'm wondering if he will actually gain much weight very quickly. With a young snake it's understandable for it to grow so fast, but most BPs slow way down on growth after their third year or so. Since Joey is at least 4 I'm just hoping to get him rounded out some, and get whatever growth he's going to go through.
Of course the first thing he did was poo and pee all over his clean tub (and that was after I weighted him so 300g - a little bit) but I wasn't thinking and just threw all of the bedding and waste out. Next time there is any fecal matter I'm going to take it to a vet and get it checked for parasites... I'm just having such a hard time believing this tiny guy is 4 years old!
Oh another note, I really don't think the guy that had him knew any better. He knew he should be fed more than every three weeks, but that was as often as he was able to get home recently. I'm not so sure about the first couple of years. He didn't seem to think anything about the fact that he was so small, so I'm going to work on educating him on BPs and be sure he has the right idea if he ever wants the guy back.
