Daniel Sherlock owns a cat named Louis who has a tendency to wander away from home and then come back again. So while Daniel was running errands a 1/4mile away from his house, he happened to run in Louis wandering around.
Naturally, Daniel offered Louis a ride back home, which he accepted with a strange, happy grin on his face. This odd picture of such a happy cat has now gone viral. Obviously Louis was happy to see Daniel and likely grateful for the ride back home.
The next time your cat goes outside, be on the look out for it. You could capture a funny picture like Louis grinning happily at the thought of a ride back home.
