I have read a few things on the internet about hedgehogs going through quilling.One thing I read was that quilling can take a week or 2 to a month and that I could give my hedgehog a warm bath. I tried this and it does calm my hedgehog more. He doesn't huff or puff while I give him a bath. But I was wondering, is it bad to give him a bath every night?

Bathe your hedgehog whenever it gets dirty or about once every few months
