Yes, we had three days of rain here but today it hasn't rained so far, but it sure is cloudy, so I'm sure were in for it again.
On rainy days, I just keep the girls in the dining/kitchen area with pee pads down. When the rain either lets up for a few minutes or at least down to a fine mist, I take them out. I just don't let them have run of the house on these kinds of days. It works beautifully.
