Magical Magnetic Noses
My cat has a magnet in her nose. My husband does not.
Dushenka is a wanderer. She wandered into our lives one day and decided to stay. Occasionally, the wanderlust still seizes her and she gives the phrase “Door Dash” new meaning. We’ve tried chasing her, with no success. She always comes back after she finishes with whatever she’s doing and strolls right into the house, where we call her “Naughty Grrl” and she remains completely unrepentant.
Then we moved, to a little apartment in a medium-sized complex. For six weeks, Dushenka showed no interest in the outdoors. Then one day, when our groceries were delivered and our attention diverted, out she raced. Naughty Grrl.
This time was even more panic-inducing. We had been in the apartment for only six weeks and we were quite sure Dushenka didn’t know her way around the neighborhood. Besides, it was 90 degrees outside and I pictured her lost and melted into a pitiful calico puddle somewhere, panting and expiring from heat exhaustion.
Imagine our surprise when 20 minutes or so later, she showed up on the doorstep (where I had put a bowl of water). I opened the door and Naughty Grrl strolled right in, as usual.
Admittedly, this story is not as dramatic as the ones about dogs whose families move away and track them down across the country. But it did get me to wondering. How did Dushenka find her way back?
Apparently, it has to do with the magnet in her nose.
Note that we didn’t put a magnet in her nose. It seems it was there all along. Scientists have discovered that various animals such as trout and migrating birds have in their nasal cells a mineral called magnetite, which, you might have guessed, is magnetic. Evidently, it allows them to sense magnetic fields such as those surrounding the Earth. How do salmon find their way every year to where the bears wait for them? Magnetic noses. (“Magnoreceptors,” if you want to get technical.)
Dushenka’s nose is tiny and pink (I have only ever seen one tinier and pinker, on a cat named Julia). You’d think there wouldn’t be room for a magnet up there. But apparently, it’s standard equipment.
Human beings ought to have the same sort of device lurking up their nasal passages, but we seem to have evolved away from that. There are tiny magnetic particles in the ethmoid bone in a person’s nose, but not enough to make a difference. Or at least not for some people.
Despite the fact that men are supposed to have a better sense of direction than women, my husband can’t find our car in a parking lot, or do that thing where you make three right turns to get back to where you started, or read directions in reverse in order to get home from an outing. He used to be embarrassed by this, but I think it’s comforting for him to know that he’s merely magnet-deficient and therefore (probably) more highly evolved. Or I as I think of it, topographically challenged.
Why don’t I get him a GPS, you ask? I did, but he never even installed it, much less used it. No, he prefers a human GPS (i.e., me) to go along with him whenever he has to trek to somewhere new. The magnets in my nose seem to work just fine, even though they can’t give directions in the voice of Han Solo.
Soon we’ll be moving back into the house where we lived when Dushenka came to us. I feel confident that when she inevitably makes a break for the great outdoors, her marvelous magnetic nose will bring her right back to us. Where we’ll tell her yet again that she’s a Naughty Grrl and she’ll flop down to rest up until her next expedition. I just hope Dan doesn’t get lost trying to chase her down.
