I'm fixing up my ball pythons old tank but I have an issue. The tank is a study plastic(was originally a bird carrier I bought 2 years ago at a flea market) but one of the latches fell off, allowing him to easily escape from it. Tomorrow I am going to buy a new latch for it but I'm not sure of what the best method of putting the latch securely on would be. It's a really nice tank for him and I'd hate to let it go to waste. Any suggestions for securing the latch?
