You really shouldn't let him play with a towel at all. Hedgies like to dig and scratch at whatever fabric they are on, so they can find a comfy place to sleep. And their little nails can get caught in the loops of the towel and end up ripping their nails.Hope said:
The only time I use a towel is bath time, but once I leave the bathroom and he's dryer, I move my boy into a bundle of fleece.
And, there's probably something tasty he likes on the towel, just be careful he doesn't actually eat any of it, or else it can cause an impaction.
