Pumpie's in love

My cat has been acting strangely recently. Coming in at all hours of the night and then sleeping it off for longer than usual, sprawled out like a spent lothario on the spare bed.

Today I think we have discovered why. While perched at my spot on the deck which might as well have a sign that reads "summer office" we hear a meowing unlike the typical sounds that are regularly audible at the 27 moments during the day when he feels the time is ripe for a snack.

We go into the yard and there is Pumpkin, gazing wistfully at a white cat with a black tail. She, the white cat, is looking back at him inscrutably. He is clearly smitten and she does not look like she minds the attention, but is not initiating. Now twenty minutes later, they are still doing this courting nonverbal dance.

What to do?

Is it time for me to have a man to cat talk with the Pump. He looks so forlorn. Should I tell him to forget her, that there are lots of cats in the sea. Should I tell him to be aggressive, "go ahead put your paws on her, she probably feels the same way about you." Should I suggest that he pull some flowers from somewhere (he won't find any in this yard, I specialize in weeds) and present them with a bow.

Not sure how to handle this situation. I wonder if the key is to just let them be and what happens is what happens. If she doesn't purr back, don't chase, there is nothing you can do. But then again, why is she in our yard? She came here. She's not a stray, there is a nametag on her neck. Maybe she is hanging around hoping for the Pumpkin to make a move.

I hate to have him moping around the house. Hope she comes across.
