Dry air is probably it. My skin has been a lot drier. However, he's changed foods several times. He quit eating what I was feeding him when he got here. Hadn't thought about the protein thing. I've been feeding him Proplan turkey and beef canned food. He can't have any dry since his operation. I still haven't found a job so can't buy a humidifier right now. Should I give him a little more fish oil?
