I gave him a bath for an easier skin analysis and he lost a few quills in the water. I didn't notice any redness, but he has been very flaky. He also keeps shaking (like a wet dog would) which makes me think he is a little itchy (no scratching seen.) I made a vet appointment for tomorrow and will bring some quills along, thanks for the advice! I didn't do an oil rinse today and haven't for a few days. I will be sure to keep him oil free until I hear an all clear from a vet!
