Please help me ... my baby Zeppelin won't eat. Its really warm here, so I think it may just be the heat, but I'm still worried. He is 10 years old and recently adopted from a friend. He is still friendly, still rolls around, begging for attention, still drinks out of the faucet in the tub, but he just wont eat very much. I tried to get him to at least eat some treats last night, but he only ate 4 and threw them up. Do you think that it is the heat, or something worse? PLEASE HELP!
