I'll try to get around to answering recent comments later. For now I'm still in babble-mode.
Something I was thinking about a week or two ago and forgot to mention here: I would be very interested in a picture of a cat, colour-coded to show the relative density of nerve endings in different areas of the cat's skin. (A black-and-white drawing with different shading counts as "colour-coded" for this idea.) I've got a couple of questions that such a picture might answer, and even if it doesn't, it'd be a really interesting picture. I wonder whether it's already been done (and is available some place less expensive than an advanced veterinary-school textbook). It would actually have to be an intricate pose or more than one drawing, because I want to be able to compare the top of a foot to the pads, for example.
Someone I mentioned this to said they'd seen a diagram of a cat with body parts enlarged or reduced to convey similar information, but from their description it sounded like the illusrations I've seen of "brain maps" which show something else (which may be correlated to some degree, but is, IIRC, a different question to start with).
Okay, sleep now; dizzy again.
