As some of you know I bought 2 snakes for $150 a month ago. I decided to house them in the same cage because everybody says garters are fine with that. I came back from a week long fishing trip and the expensive one of the two was missing. I found no cracks or holes in the lid and I VERY strongly doubt that he could push the top up at all, since he's not even 9 inches yet.

Is it possible that the other, same size, same species (Sirtalis sirtalis) ate it? He was slightly more aggressive than the one that got eaten, but he didn't appear to be any larger than normal.
