i have a row of the grids loose, and tied together, and i keep it locked with a pad lock, because anything else, roby will get open, hes an escape artist, it seems they are getting along, but since i made it bigger, they havent been eating as much . is this because they are using more energy, o wait, that would cause them to eat more, are they eating less because they are less bored to overeat? i dunno, its like they refuse the pellets lol, but they LOVE when i give them veggies.
