so the new viv we built we were trying to figure how to put the cords through without a million holes. so all are run down to one corner and fed through. Well,the hole had to be big enough to fit the plugs and once the plexi-glass was placed over it I had thought, no problems....well I was wrong! 4'x6" was thier home, under the viv with no escape but back up and in. Happened to walk past and say WTF theres a white snake! and then watched her go back down the hole. We have now fished both girls out and they are secure, watered and I can remove the various bottle traps (that have been driving my cats crazy BTW)from around my house. YAY!
