When Cathleen Cavin first brought her daughter's kitten, Ozzy, home from a Petaluma, California, animal shelter in 2014, she felt guilty about separating the cat from his brother. One day, she promised, she'd reunite the siblings. Two years later, Cavin met Brian Herrera on Tinder. The pair hit it off, she went to his home — and was shocked to find that his cat, Butter, was a dead ringer for Ozzy. A check of shelter records revealed that, indeed, the pets were long-lost brothers. "It's total destiny," says Cavin, who's moving in with Herrera next month. "Yeah, it's fate."
