That's awesome John! Are you planning on sticking with gerbils, or are you going to try and switch back to more traditional rodents once his appetite is firmly established again?

I'm finally breaking down and plan to buy some live fuzzies from the pet store tomorrow. Hopefully Caesar will eat those and regain his appetite, too. He's still active when held and seems "normal" but I'm growing more and more worried about him. He hasn't eaten since early Dec. This probably belongs in the colubrid area, but it seemed relavent to your feeding issues.
