I just went to change the water in the milksnakes cage today and found that the lid was open about a half of an inch. The terrarium is one of those with the sliding lids that can lock.I looked under the hides and ran my hands through the bedding and found that my snake was MIA

I started a search, looking behind the oven, refrigerator, bed, in the closet, and trying to get into the nooks and crannies you would expect to find a snake... nothing yet

Last year and while I had the snake before, I had a lock on the cage because I have other people in my apartment besides me... I'm in a studio now, and I decided not to keep a lock on it in case I lost the key for some reason... Now I see what a mistake that was

Currently I'm heating up a small mouse, I was going to feed today anyways, and I'm not sure what to do next... I don't have flour, I should be able to get some at the store tonight.

I'm in an apartment and the front door has a gap that is just over a quarter of an inch by a quarter of an inch so I really think, and hope, that Vegas is still in my apartment... It's such a small apartment that I'm having trouble finding places to look...

I would appreciate any advice at all
