My kitten, Dalla, was nebulized many times while she was at the emergency clinic last April. They thought that she had asthma (ended up being lung cancer) and the best way to get the medication in was to let her breathe it in. They had her in an oxygen chamber all weekend and used a nebulizer to add the medications in as needed. I'm not sure if this helps, but let me know if you have anymore questions and I will try to help!
