Extra Measures to Prevent Escaping?

[smakemom]

So, tonight, my ball python escaped. He is safe now and secure, but dear god, I must have lost at least twenty years off of my life. He was completely out and hanging off of a wall fixture. I could've screamed.

I'm fairly sure this was due to me not properly locking the tank (it is a click-into-place lock) because when I locked it properly and tested each door neither one budged when pushed against. I pushed to the point where I felt that if I pushed any harder it would break, and it stood firm. My bp is a young adult of maybe 3 feet- he is not that strong. But, I'm now paranoid. I have two heavy things propped against his doors so I can at least believe that it will hold, lock or no lock.

I have a tank that opens from the front and not the top. Does anyone here have any ideas of what I could do to amp up security and prevent escape? I was extremely lucky tonight. My cat was literally sitting just outside my door, and I happened to be bothered enough to check what the noise I was hearing was coming from. I want to do everything I can to keep this from ever happening again.

thank you!
