Charleston Connor Kenway NCS15 - waiting by Pearlite
I was thinking about getting mice, is a 20gal okay for 1-2 mice/1 hamster and what live plants would be good to put in that would be safe? I was thinking wheat grass (if for mice), but I wanted to make sure it was safe, as well as some other options. What natural substrate would be okay for both the mice and plants? Can I use organic potting soil or would that not be safe for the mice?
