Yeah.... I really don't understand people who do that. I LOVE dogs, but even I recoil when my puppy tries to lean in for a kiss. On the cat's paws in the beer, I would wonder how the scientific theorem of the Law of 5 Seconds applies
Scientifically, I think cat paws are grosser, but emotionally, dog kisses are grosser. Live animals are gross all around. Especially hedge hogs.
