I recently adopted two new rats. They were feeders and I knew there was a risk they would be sick. Low and behold, both of them are sneezing, one of them is worse but I think its because he's older. Luckily we do have a vet friend, they aren't very knowledgeable but it's our best option. We have ordered a nebuilizer and plan to treat them that way, but I've ran into a problem, that being they're not ready to be handled yet. I'm afraid putting them into the nebuilizer chamber will make them afraid of me and destroy all the progress I've made taming them. Since it's going to take a few days for the nebulizer to get here I've been covering their cage with a blanket and putting a pot of hot water under the blanket to steam their cage and hopefully aid their breathing a little. I was wondering if I could do the same with the nebulizer? or is the risk of mold too high?
