The Penthouse Suite

There are three levels to the Rat cage.

1. The bottom where all the poo happens, and where the cardboard tubenest is, and the play tube
2. Mid level platform, where the food bowl is. From there to the top platform, is a tube.
3. Top level. Nothing much here right now, because the ratspush everything off onto each other's heads from up here.

I put in some brown paper folded into a bag for the girls to play with, chew, tear, hide under, use in the nest, etc. Trudy immediately started hanging out of thetube and tried to drag it in with her.
It seems that she's decided all the tubes in the cage are nest areas - she's often found curled up in the top tube.
I'm not sure what makes them move up there - maybe the other nest gets too warm, maybe Oreo irks Trudy who goes off to get some peace, and Oreo comes looking for her in case there's food or she just wants a snuggle...
This time I caught them settling down an took a few snaps:
