My first, horrible thought was that he'd pegged out, calgor had come in and found him and taken the corpse away to spare my feelings. Luckily Nigel arrived a few minutes later and denied this, which left the less awful but annoying and worrying option of my having left the lid open (I left this morning in a state of considerable stress, on not much sleep) and Point having escaped to parts unknown.
I suspected that if he was to be found at all he wouldn't be too far from his nest, so we carefully removed the junk from the storage area around the cage and were soon rewarded by the sound of scrabbling.
We ran him to earth in an old pillow - really in it, having chewed not only through the case but into the pillow itself to the cosy stuffing. We had to slit the pillow with scissors and remove the fluff before pouring Point back into his cage. He's in there now, doing indignant Predator Alert hind-leg-thumps.
Wretched horrid little fat bastardy wretch!!
