I recently took in some foster cats, a mother and her eight kittens. The rescue I got them from failed to mention that they had upper respiratory infections and, since I didn't know about the infections, I wasn't treating them. The mother cat's URI has now developed into pneumonia. I took her to the vet as she began to wheeze and drool. The vet gave her two shots, a steroid and what I'll assume was some antibiotic. We go back tomorrow for more treatment. While we're at home tonight, I'm not sure what to do for her. She just sleeps, she won't eat, she can only breathe out of her mouth, she's not drinking. I want to know if there's anything I should/could do for her tonight. I thought about letting her sit in the bathroom while I showered so the steam would clear her sinuses, but my mother questioned what the moisture would do to her lungs. So I have absolutely no clue how to help her right now and any advice would help.
