Yes, every night they run out there and zoom around sniffing to see if any of the street cats have been loitering on the roof. There is one that sleeps on my red chair most nights, Cuba and Molly sniff that chair inch by inch. Because I don't want them to catch one of the cats, I turn on the lights and rattle the door before I open it, very disgusting to the dogs as it spoils everything. Occasionally we see one jump the wall and they get super excited. Of course, no self respecting street cat would stick around to greet them but they don't know that.
