Thanks, Elyse and Maggie. I just got back from the vet's with Poppaea. He did a couple of x-rays. The good, GOOD, GOOD news: No Tumor! which he had suspected as a possibility, lymphoma or myeloma (?).

The not really that bad news, there is wear and tear showing on the cartilage connecting the ribs to the spine, which he said probably makes breathing harder or painful for her. This is an old-cat kind of development, and she's at least 18 years old, more likely 20 or more.

He told me to bump up the Azithromycin (not Doxicyclene) to each day over the weekend, and he gave her an injection of Depo-Medrol and said to call him on Monday with an update.

He also thought the steam treatment could help.
