On Reddit, a cat owner going by the name Lazy-Squish posted a picture of her two cats and challenged people to tell them apart. Now this Reddit post has been viewed by over 40,000 people who have offered ways to tell which cat is which.

The two cats, named Pebbles and Rocky, are female and male. By closely examining the image, you can make out slight differences between the two cats but it takes a trained eye to notice them, which means both cats could cause trouble and blame the other one just like real human children would do.
