PS: No sooner do I post this than I find he's deleted again. Never mind; I have reason to believe it's only a temporary expedient.
PPS: Ignore the postscript. He hasn't deleted again. As pondhopper kindly pointed out, I got his name ever so slightly wrong. This has now been rectified.
PPPS: Actually, ignore the post-postscript, it seems that there are two ferrets- one who has deleted and one who hasn't. My ferret is still gone. I think.
PPPPS. No he hasn't. And that's because he's not a ferret but a ferrett. Sheesh. Thanks to purple_pen for pointing this out.
