Answer
Hi,
I would take him to a very IMMEDIATELY. It could be life-threatening, so unless you want to risk him dying, you really need to take him to a vet.
It may be the bedding, so change it as soon as possible too. Have a look at his skin. Are there black dots or flaky skin? If so, he may have ticks, fleas or mites. You can buy "Spot On" which treats it.

I hope he recovers soon.
Best of luck,
