How good are Corns at escaping?

[Lolo76]

VERY GOOD!! I know because I've had two escape, one of which still hasn't been found. The first was Scout, my little reverse okeetee, who managed to squeeze out of a locking 12qt tub... thank goodness I found him quickly, just a few feet away in the closet. Then I had one escape on a car ride (coming home from her former owner's place) - but that may have been our fault, since I'm not sure the tub was tightly closed.

So yeah, I'd be awfully nervous about any tiny gap! I added binder clips to Scout's tub, since I'm not taking chances after his escape attempt... apparently even the locking Sterilites aren't secure enough. As for the holes, I just do one row all the way around (about 1/2 inch apart), maybe two if I notice humidity issues.
