Sounds like they are doing everything for him. I had a child who was very sickly-if he got a cold-he would get pneumonia. Was in hosp several times. We kept a humidifier in his room-and also did the shower/steam as David suggested. Perhaps, when Chuck gets home-you can ask your vet if a humidifier would help. So glad they are having a plan to treat him as they are! Praying for your little fella'. He is so cute! Be strong, Chuck!
