When my cat's sleep, they whistle when they breathe. It's through their noses, it's not loud, but I can definitely hear it. It is not new, they have done this for a long time. We have a humidifier for the whole house, plus an additional warm mist humidifier specifically for this room, because this is where the cats sleep all day. I don't know what else to do for them. Any suggestions?
