My California king snake has been missing for approx. 24 hours. I recently put him in a new cage with a lid that does not lock. The lid had weights on top of it to keep him from escaping. Unfortunately, he must have squeezed through the tiniest of holes in the top (it's so small I overlooked it, thinking he could never fit through something less than 1/2 his size.) Anyhow, my apartment is in shambles now that I've torn it apart looking for him. I kept him in my rather large living room, so he could be anywhere. There are 2 heating vents in this particular room, and I'm worried he crawled in one because it's warm and dark. He is so small, I just don't know which nook or cranny he could be hiding in. Does it work to set a live mouse in the middle of the floor in some type of contraption with a pillowcase over top? Last January when my corn snake went missing I put the top end of a 2 liter pop bottle inside of the bottom end with a dead pinkie inside and I never found my corn snake before I moved from that apartment into my current one. I will try ANYTHING. I cannot lose another snake. My lease is up in August and we're moving AGAIN!
