Your Cats magazine, in England, held a contest, sponsored by Friskies UK, for the cat that learned to do the best "high five." I was the judge. There were so many entries (by photograph) that we couldn't pick just one winner. Here's one of the entries, and you have to agree, it's a quintessentially British scene. I don't know who's having more fun, the cat or the owners.
Here are the top contestants.
