Thanks everyone!

Just a little update about the cage, the gerbils are doing great in it. Ebony has more energy than ever and Twilight is digging tunnels for England It's also benefitting Nightshade.

In the previous cage, the gerbils used to chew like crazy as I think they were getting a bit bored not being able to dig that much. Nightshade had a habit of chewing the bars, and she chewed them so much that a small patch of fur was beginning to rub off on her snout. It was only a tiny patch, and of course, nothing serious that caused her pain, but was beginning to look a little odd. Now, with plenty of digging to be done, the fur is growing back and she looks fine again.

I tried to take a before-and-after pic, but if you've ever tried to take a picture of a gerbil's nose with a mentally challenged camera, you'll know how hard it is!
