I'm not sure if "odour control" means the bedding has some kind of perfume/scent in it, if so this could be causing a skin irritation. If at all possible I would switch to liners, to see if the itching goes away. Treating with revolution for mites as a preventative may also be a good idea, here's a link: viewtopic.php?f=5&t=2628Hope said:
Or the little one may just be quilling and have dry skin. Try bathing in aveeno oatmeal wash, either the unscented baby version or the regular. With quillers, you can bath as frequently as every 6 days. Also try getting some flax seed oil capsules (not the oil as it spoils easily) and breaking one open and using it in your last rinse of the bath. They can also be used on the hedgehog when dry and broken over the food (but no more than one capsule per week kinda thing).
What kind of food is your hedgie on? A high quality food promotes good skin and overall health.
