They have been growing like weeks! I had to make a new place for them to live. I took my exercise pen and lined it with plastic and now they have lots of room to run around My hubby also came up with a brilliant idea to keep them from making such a horrible mess with their water! We bought a big plastic pot base and a recycled rubber tree ring and a couple small bricks. put the bricks in the pot base to support everthing, then the tree ring which allows water to soak through it and the waterer on top of that and it has been working wonders!
