You can befriend a dog by letting it smell you, but you can make a cat love you by offering it your earwax. Is this kind of disgusting? Yes. Does it actually work? Apparently it does.
Redditor and former animal control worker sirdrizzzle makes the tantalising suggestion:
Ex animal control person here. To win it over in a pinch, stick your finger in your ear and give it a twist, cats love earwax.
Of course, you also have to take your finger out of your ear and put it in the vicinity of the cat (but that's a given, right?). This may seem a little insane to those unfamiliar with cat quirks (like myself) but the cat-earwax phenomenon is apparently very common. If you look at Yahoo, the PetsWelcome blog, Ask.com, Answers.com, Is It Normal?, and The Cat Site, you'll find plenty of evidence. There's even a blog named after this circumstance. You can also watch the video above for a real, live demonstration!
So, if you need to make friends with a cat, stick your finger in your ear. Seriously.
