cat tails

I.
our cats are having a fight. it happens at least once a year and the scenario is always the same: the black cat (known for her adventurous spirit and generally grumpy disposition) comes home smelling funny. the tortoise cat (known for her extreme stupidity, lovely disposition and utter unwillingness to venture outside) does not recognize the smell and assumes this is some foreign cat trying to invade the kingdom. Big fight (with blood-chilling screaming chases through the house in the dead of night) as the tortoise attempts to remove the intruder.

a few days go by. the black cat's smell returns to normal. the tortoise, delighted to see (or rather sniff) her long-lost friend, makes overtures. to no avail. 'yeah right!' seems to say the black, 'like i'm likely to trust YOU again...'.

why does this remind me of people's fights?

II.
Isabelle wanted to know why the cats were having a fight. i explained.

- ... but Likkepot (tortoise) can see it's Minou (black), can't she?
- yes, but Minou smells different. with people, the eyes are more important than the nose, so if a man comes in who smells like Papa but doesn't look like Papa, you will think it's not Papa, and if a man comes in who looks like Papa but smells different, you will think it is Papa, right?
- yes...
- well, with cats, it's the other way around, the nose is more important than the eyes, so if it doesn't smell like someone you know, it's not someone you know...
- ... oh, so she doesn't know it's Minou?
- no.

... and that got me thinking, about this 'knowing' business. why do i so easily assume that the cats are wrong and i am right? why would my reality be more real than theirs? when i was pregnant with Isabelle, i thought Marc smelled funny. i didn't want to lie down next to him, and generally avoided being within smelling distance (not easy if you share a bed, a 40 square metres house and an unborn child). i assumed it was still Marc though. but what if it wasn't, not really. what if changes in smell indicated changes in other things, things that influence how someone behaves or responds, and who they are?

(and what if it was time to quit these philosophical feline musings and get my sorry ass into bed????)
