Sorry, I meant that the mice had chewed a circular hole in the tubs. I think that the tubs are the new van ness ones. I got them from walmart and I think that they come in blue, green and a maroon color. Are those crappy or something? The gap b/t the tubs and the screen is less than 1/8 of an in on all of the tubs and even on the ones that it fits snug, the little guys still chew a hole in them.
