Miracle liner for pet cage and anything else

The miracle liner is polyester film such as Duralar.  It's like a sheet of paper but made of clear plastic instead.

The miracle?  It's easier to work with than paper.  It is tear and scratch resistance.  It stays flat, better than non-slip.  It's heat resistance and chemical resistance.  It's low cost.

Even if you brought a huge roll, it stay flat when you unroll it.  I know because I used it to cover the whole dinning table.  It's clear and you can write on it.  You can put it on a table or on the floor with a grid pattern on it.  It's extremely easy to align and measure the exact size.  Or you can trace the outline of the cage, or you can just cut freehand until the sheet fits the cage.
 
The sheet is slightly too thick for a paper cutter.  But it's extremely easy to cut with scissors.  It's easy to cut while following a straight line.  It's easy to make a smooth cut whether you cut is straight or slightly curved in multiple parts.  And since it's clear plaster, it's hard to notice that the cut is not perfect.

If the cage floor is reasonably fitted with a sheet from wall to wall, it's very difficult to take the sheet off because it stays flat from edge to edge, corner to corner.  My bunny toss everything and attack steel wires but he couldn't do anything to the sheets.  If the cage has some sort of "wall", it's better than non-slip liners.  It just couldn't slip pass the walls.

The sheets are extremely easy to clean.  I used rigid sheets before such as acrylic.  I have to soak them in acid to get the rabbit poop off.  It's a lot harder to cling onto flexible plastic sheets.  When the poop are dry, they will almost fall off by themselves.  Chemical free.  I suspect that there is something to do with it's diet and the strong sun.  In any case, this material is the most easy to clean stuff I ever used.  It will return to it's flawless clear state after cleaning.

Because it is cheap, I stack several of them.  It's non-slip even when stacked together.  When the top one gets dirty, I just lift it off and expose the 2nd sheet.  Then I dry the dirty sheet in the sun.  If you want to wash it clean immediately, you need some acid such as vinegar and citric acid.  Or, you can wipe the poop off with tissue paper whenever you see them.  It's almost perfectly clear again once you wipe it.

The sheets are slippery so the naughtiness of the bunny is reduced a little.

My cage floor is made with perfectly pre-cut to size wood pieces.  Polyester sheets are the perfect liner for that.
