On the subject of fat fuzzies getting their heads thru holes their butts won't fit: These guys don't have a very accurate self-image and almost no regard for the laws of physics. There are a variety of household objects that should be closely examined for potential square-hole/round peg problems in addition to those wonderful storage space solvers, the plastic crate. Please check your: Laundry baskets, wire shelving, plant stands, bed headboards/footboards, & magazine racks with "V" shaped wire legs or decorations, baby security gates (can be covered on both sides with contact paper), paper towel, toilet tissue, & wrapping paper rolls. We had one boy who decided he could fit thru a 1"x1 1/2" hole in a wire shelf. We had to cut the wire to extricate him. He had bloody poops the rest of the day (severe stress reaction, for which the vet administered dexamethasone). Needless to say, some tight fits can and have been deadly.
