Chibi was one of Kathryn's cats, but developed cancer. So she joins Inari and Jita and Pepper in Zone 2.
Zone 2 has filled out a lot since Inari and Jita were buried in 2014, but we continued along the kitchen/garage wall. This put us into the Monkey Grass.
But Monkey Grass is resilient so we expect it will fill back in, over time.
