So. When the girls were trapped, they were in sad shape. Bad colds, eyes crusted shut... I got them after they were clear of the cold, but Luna was "hocking up a loogie" or trying to - yes, it sounded as awful as you think it sounds. Although I've put on the humidifier for her, she was still "snorking" this week. After a chat with a friend and googling "Nebulizer" and "Kitten Cold" - I cranked up the heat in the bathroom, took a hot shower to steam it up, and took both the vaporizer and Nebulizer, and the kitten into the bathroom with me. I put in a vial of albuterol, diluted it about 10x with saline, and directed the output at Luna.
I'd not thought the Nebulizer loud until I had it in the bathroom. Kitten was properly wary of it, so after the liquid was all gone, I turned it off and cranked up the Vaporizer. I think she understood what was going on, because the moisture laden air did help. *snort* *snort* *sneeze* and out came the mucus. Here's a photo of Luna sitting in the stream of moisture coming out of the Vaporizer. It cleared my lungs too.
