So I have an opportunity to locally get a Mexican Black Kingsnake from a local pet store. It looks cool and I think it's a female. It's currently overpriced, but the pet store owner since I go there often for crickets and to sell my normal babies, etc promised me a discount.

But I also own ball pythons and lizards and Mexican Black Kingsnakes are known escape artists. I'm planning to upgrade my ball python female to a 4' enclosure, which will leave the 3' enclosure open. (She's about 5-6' long so I feel bad keeping her in a small caging.)

So... umm... how much of a worry is it that your Mexican black kingsnake will escape and eat the rest of your snake collection if you've been feeding it frozen/thawed rodents? Or is that a stupid worry to have?
