I have to say I cringed too, but just put that what you see isn't always a true indication - I remember with Snowy, I thought she was looking quite thin (she had liver probs), yet everyone who came to the house said 'oh, she is fine, it is just old age', and even when she started picking at her food (not that unknown for her), my neighbour (who I still looked to for advice then) told me it was nothing to worry about, when I had her blood tested, it showed that her liver prob had got worse, and even the day before her final visit, she looked fine - if I showed you her final pic, you wouldn't know there was anything wrong with her at all, yet she had a liver prob that hadn't responded to meds, and even by feel, her liver had got worse in a 2 week period. Admittedly, this is highly unlikely to happen in a young cat, she was 13ish. And PEbbles had 3 blood tests cos even the vet was convinced there was something going on by the look of her, yet they all came back clear, so it just shows you never can tell.
