Has anyone made one of these and had problems with chew outs? I have recently made one with the exact specifications and there is about an 1/8" gap between the tub edges and the wire/ wood. Some of the mice figured out that they could fit their mouths in there and chew out of the container. Many of them just chew a hole and don't do anything, but there are a lot of tubs that are getting chewed and at 3$ a tub it is kind of getting irritating. Anyone got any solutions to this? I could put 1x4's under all of the tubs to make them tighter but that would cost a lot more. Any help?
