Hey SP, I'm just about done with work for today ~ yeh!!!
I bought Four Paws brand Bunny Bath for my girls. It's mild and won't lead to dry skin (supposedly). It smells good, but doesn't last long.
The best thing I found to keep the pigs smelling "fresh"

is to give them a fabric tunnel fresh outta the dryer after I used fabric softner on them. April freshness
I use the hair drier to get them started on their way to being dry, but then just put them in the "hot" room and watch them shake it off! That's so much fun!! I make sure all butts and bellies are completely dry though before they go back to their cages.
