Kitten today, sock eating monstrosity tomorrow

The kitten has grown. Just look at it! It's really rather immense. Turn your back for a weeks worth of hungover self-pity and this happens.
"What on earth has it been eating?" I asked, slightly hysterically, looking through the fridge.
"No furniture's gone missing," called my Alec Flatmate from the next room, "and my socks are all present and correct- you might want to check your wardrobe though."
Good lord. I imagine there are parents out there who feel the same about their children- is this what they mean when they say children grow up so quickly?
I don't call eighteen years quick though- I'd rather have a cat; but I haven't found any missing clothes yet, so this might change.

I realise it's not quite on the same scale, but it's the closest I'm ever going to get to the whole 'real parenthood' thing- and I really am a remarkably bad cat parent, so thats probably a plus.

Anyone like to take a stab at whether it's a boycat or a girlcat? I really have no idea, but I have a feeling it's something I should know.
