A Fancy Feast catfood commercial.
Young man visits girlfriend's parents, sees her attachment to the family cat.
He repaints, rebuilds, redecorates a room in his house, adding astroturf and a feline pic. Buys a fluffy white little kitten and installs it. Leads the girl into the room blindfolded.
On opening her eyes, she gushes, picks up the little cottonball thing and finds a heart-shaped charm on its collar, which says: Will you marry us?
She gets two pussies for the price of one.
