The Great Escape
Monty has been biding his time. For two and a half years now, he's been planning this, exploring every inch of his cage, delicately probing at the lid. And Sunday night he decided that it was time to go.
Somehow he pushed the lid up and got himself through the opening in such a way that it fell back into place. Then he presumably spent some time exploring, before settling down in the nice, cozy spot behind Allison's dresser.
Now, a couple points here. Ball pythons might seem intimidating to people who aren't big into reptiles, but they are super gentle and harmless. If they are bothered they don't bite, but curl up into a ball (hence the name). So nobody was in any danger here. As far as I have been able to determine, there is no record of a ball python ever injuring a human.
