Wrens Leave Nest Today

I am packing today with all my cats in the house.  I went out onto the porch this morning to feed the cats and the wren family was scolding me for having so many cats, when they needed to push their babies out today.   I just got a glimpse of the last baby leaving the nest a few minutes ago.  I will give them a few hours to get safely away from the house before letting the cats out.  The cats are well aware of what is going on and they are not happy to be indoors today.
