Liners are the best.
I ordered 1 so I could try it. Soon ordered another for easy cleaning only it didn't work out that way. I upgraded my girls' cage with a mezzanine and didn't even think about the liner for it. Even though its way too big I wrapped my second liner around it and it works pretty well for now. I have the mezzanine-sized liner on the way and am looking forward to being able to do just a quick switch between liners. My girls love to jet around and popcorn and keeping up with the pine being thrown out of the cage was just ridiculous (also, I didn't know that it can cause allergies for piggies!). I have a section of coroplast as a "kitchen" that has a less dusty paper-type bedding and that still gets kicked out but not nearly as much as the full cage using a loose bedding. I didn't have the opportunity to wash them before use but they seemed to work well even without the initial wash. Found one little puddle but since washing 1-2 times have not had an issue. I don't notice any smells so far but have white vinegar on hand if they need a wash with it. I take my girls out of the cage and use a dust buster to pick up all the poos on the liner between full cleanings and change the kitchen bedding 2-3x a week. :)
