Tyler, my latest goofball addition to the furry family has got himself
stuck down behind my corner bookcase.

All of my cats have explored down there at one time or another. The
bookcase has shelves that extend along the two walls of the room, with a
section of shelves that sort of cuts across the corner of the room on an
angle, if that makes sense. There's a gap behaind that angled section
that's big enough for a cat to climb down, but it's really difficult for
the cat to climb out again as the back of the bookcase is smooth, and he
can't get a toehold.

My usual way of extracting a cat from this corner has been to hang my
very large bath towel over the back of the bookcase and encourage said
feline to climb up it. This they normally do with great enthusiasm. All
of my cats have got stuck and been removed this way once (in fact Sir
Stirling the Silly has done it several times).

Tyler won't. He is sitting very quietly at the bottom of the triangular
space, and occasionally washes himself, but I can't persuade him to try
and climb out. He looks calm, but he could be stressed. Or he could be
enjoying himself in his new dark den.

Any suggestions? I don't really want to have to violently dismantle the
bookcase - of course I will if the little beggar, sorry, little
sweetheart, can't be persuaded to help himself out by dinner time...
