Fleece does not fray.

I would cut the fleece an extra six inches on each side so you can fold it around the towels. But if you already cut it, whatever you have should be fine.

I wouldn't bother with the newspaper. It won't really help, but it will get messy.

And yes, after this it is just one wash/dry cycle each time you clean the cage. The fleece will get better at wicking over the next few weeks though (as it gets washed more), so if it's not perfect at first, don't worry.

And yes, a layer or two of towels and then the fleece will be just fine. If you notice the cage smelling, try adding thicker towels or more layers of beach towels, as beach towels are not the most absorbent. How well they work will depend on your pigs and your cage.

Also, I recommend a litter box in the most commonly used area.
