I have a lot of extra toys/blankets/hammocks and stuff from previously running a ferret shelter. I don't do fleece liners, my girls dont like them. Instead I use one large fleece blanket that is folded and put on one floor. (just those cheapy fleece blankets you can get at pretty much any dept store) Buttercup likes to sleep on top of it. On the bottom floor I use a play mat, I have a few human baby and animal ones. the DCN has plastic trays that sit on top of the wire, so if yours pee in places other than the litter box, you can just change out the bedding and wipe down the floors. Once a week soak them in a vinegar/water solution along with all the other stuff. If you are looking for an even easier solution for quick clean ups in-between the big weekly, you could buy the nature miracle wipes and use those instead of making a solution. I have to pinch my dollars, so I make my own solutions and use rags to clean/wipe down stuff.
Wicker baskets I pick up at the second hand stores. Wooden blocks, balls and such we either get them in bulk for making your own, craft stores or we just cut up our own safe woods. I make a lot of toys with those/sisal rope/large plastic beads and bells. My girls like to chew wood, so I like to have a lot of extra's. Places to dig is nice too for most-some kind of nesting/dig box. I use materials that can be easily tossed when they get soiled. Go by what your's like. Mine like any kinda of paper-such as newspaper, party streamers, packing paper, toilet paper ect-they like to rip it apart themselves. They don't like the already made paper pulp type ones, but other rats love that stuff, so go by what your's like.
I only leave a few things in the cage from a previous week, mostly the whole thing gets changed up with different toys, hammocks and stuff. Mine are not timid and they really like to investigate new things. I do leave a few favorite items from one week to the next. Monkey loves her plastic super pet tunnels-those are cleaned and dryed and put back in. Any hammock that is not smelly or dirty I also will put back in-so there area few familiar items for security and lots of new things to explore.
I only have one pic of the top half of mine, but this is it. The bowl on the door is a toy box, filled with things to stash and chew up. the plastic rings towards the back has party streamer looped onto it for them to remove and use as they see fit.
