It used to be that having a cat paw appear in your drink was as easy as leaving your mug unattended on the kitchen table.
Now, thanks to revolutionary Japanese technology, you can have the same effect (sans cat hair) with a magical marshmallow that dissolves in your hot beverage, leaving the illusion of a pink paw pad floating in your hot chocolate.
Well that explains everything!
Despite my best efforts, I couldn't figure out where to purchase these handmade delights - however Google translate was able to provide the following information: "Cat meatballs marshmallow" is launched by a Japanese specializing in selling cotton candy stores や wa wa da", the "cat meatballs marshmallow" is not directly eat to soak in the warm drinks inside."
Update!: Susan was able to provide the correct translation! She says, "The name of the store is Marshmallow Senmonten Yawahada. "Senmonten" means "specialty shop." It looks as if the store is located in Nagano Prefecture. You can order from the store's website: http://sanpasta.ocnk.net/"
