Hey guys, I just moved my snake from a pretty small glass tank to her new permanent home, a 41qt tub. My first question is, how to do you guys secure the lid so we don't have any escapes?

Also the tub is clear, so if i walk by to fast and she's poking her head out she jumps right back in her cause I scared her, she didn't seem to so that in the glass tank... and ideas why?

Lastly my snake poops/pees a lot. She pooped/peed twice yesterday, and peed while I was holding her about 4 days ago... Is this normal?

Thanks for your help!
