I've been experimenting with different cage setups and combinations of beddings. The current one has a thin tray (no bedding) on the floor to cover the wire on the first floor and fleece on some of the second, though some wire is exposed. They like to stuff newspaper in their hideouts and also have a litter tray. All had paper bedding at same point and I never saw 2 of them burrow, however the new ones did at the pet store. I gave them a large box to test their interest but no one seemed to care. I don't want to waste time & money when I could use it for other things they like. So, is it that important? I also still have 75 liters of paper bedding left so I could try another layout.

The purpose of any sort of bedding is comfort, hygiene and odor control. A good bedding should reduce your pets' contact with their own waste. It will absorb urine and minimize direct contact with feces.

Bare floors, whether solid or wire mesh, should be avoided.

Would tarp be enough or should I use something softer?

All bedding does is absorb urine and odors and provide a comfy soft material to sleep on. Bedding doesn't allow for burrowing unless it's at least 6 inches deep. It's not necessary and some rats may not care for it. Fleece with an inner absorbent liner works for many people. Just clean the cage regularly to keep everything clean and urine and other odors down.

Crinkle paper is great for burrowing and nesting. I do a combo of crinkle paper mixed with bedding and also have fleece liners.

Do you know if puppy pads would be safe as an absorbent liner, as long as they're not in direct contact with the rats?
