I have pet birds. I still can't sleep on down pillows - one night and my face blows up.
the best down pillows out there, though, in my brother's opinion are from Landsend, I believe these are them (be prepared for sticker shock, make sure you are sitting down...)

My brother made me buy him one to have at my house or he wouldn't visit me.
