The Stuffed Cat is cheapest of the four date gifts that can remove all Broken Heart tokens from the grid. The other three (the Stuffed Bear, the Stuffed Penguin, and the Stuffed Whale) convert Broken Hearts into something else whereas the Stuffed Cat simply removes them, often drastically rearranging the grid, depending on the amount of Broken Heart tokens removed.
The amount of occurring Broken Hearts can be increased with the Lilac Perfume.
