One of the issues we had with the wire floor cage was the trying to find something to attach to the floor that would protect the rats feet, be light weight and easy to clean, not easily destroyed by rat teeth, and here's the hard part.... attractive. Or at least not completely ugly.
I searched high and low on the Internet for new ideas. Some use tile, linoleum, cardboard (did I mention I wanted it to be durable).... anyway, I didn't like any of those ideas. Many people use fleece, the problem was that even with two layers sewn together, I wasn't happy. Though I knew they were probably fine, I could still feel the wires by just lightly resting my hand on the floors. The other problem was how to attach them easily to the floors and ramps without them getting moved around or chewed.
And then it came to me, plexiglass. It's very durable, relatively inexpensive, and the best part - clear! I bought enough for all the floors and ramps, a special cutting tool, and some extra zip ties. In the end I think I maybe spend about $25 on the whole thing and I am confident it will last a very long time. So I cut the pieces to size, not an easy task but it only took about 3 hours total. I drilled 2 little holes in each corner and used small zip ties to hold the floors and ramps in place.
Here is a picture of what one of the floors looks like....
You can also see I have some velcro on the corners. I bought velcro that is sticky on one piece ( for the plexiglass) and sewed the other connecting piece to fleece that is cut to fit. I have fleece covering all the plexiglass surfaces to make it easier for the rats to climb the ramps and so they don't fall from the ledges. To clean the fleece all we have to do is rip it up and throw it in the wash! So easy a 6 yr old could do it- my 6 yr old ;)
Also, Em has made a fun play ground for the rats. She made it all by herself and I think she has done a really good job. Here is a picture of that -
She has actually added even more to it since this was taken. I'm sure they will love it.
