Got this covered round kitty litter box (hoping the lack of corners confuses Nima enough not to piss in there)
I added the bumblebee fleece bc the ramp looked slippery on non- paw padded feet (plus I wanted it to look cute)
Filled it with shredded paper (used a different bedding than what I use for litter so they don't think it's litter box number two.) And tossed in freeze dried strawberries, some pellets, and put hay in there too!
Assembled that thang (I can't wait for digging without the mess)
I’ve seen too many good web pages disappear so I’m reposting this cage mod description from AcroRATics here. You can follow this link for a detailed description of how the mod was constructed.

A panoramic view.
A straight view down the longer tube.
The digging box contains oven-sterilized topsoil and cat grass (wheatgrass).
A grow lamp on a 12 hour timer nurtures the grass and provides a daylight feel.
Right cage top.
Right cage bottom.
Left cage top.
Left cage bottom.
The tubes provide just enough room for any two full-grown rats to pass each other.
Some squeezing may be required...
The rats love to forage for the grass seed.
Although they explored the tubes very cautiously the first day, they now scamper through them at incredible speeds... especially if it's feeding time :3
Soon.
A later round of grass in the digging box. The ramps were removed to allow better digging opportunities.
Once the grass is gone, the rats go to town creating elaborate burrows!
Enjoying grapes.
Bosom buddies.
Feetsies.
Olive guards the tunnel entrance.
Nested in the flower pot.
An alternate configuration used while the digging box is being changed.
Photograph demonstrating the tunnel design. Horizontal bars were cut to allow a small section of 4" schedule 40 PVC pipe to fit through. The pipe is secured tightly inside of two closet flanges of the 'over 4 inch' size. The clear tubes are constructed from 4.5" OD extruded acrylic, with PVC couplings glued to the ends. Note: It is impossible to slide the pipe section through without extensively sanding the inside of the flanges. Please don't cut your cage bars trying to recreate this setup unless you're certain you can first accomplish this! See here for more details on this project's construction: http://imgur.com/a/1s5aH.
A variety of fittings can be attached, including caps should the cages ever need to function independently.
My girlfriend and I have a Critter Nation and four rats each. We moved in together and Brady Bunch'd them. With the help of a friend, we created this cage mod to connect the cages along with a suspended digging box to provide them with enrichment.
