What is the weight proportion for humans and cats?

I was wondering what the weight proportion for humans to cats is? I know I saw something like this at a vets office for food but I was wondering the weight though.

Hello - please will you tell me in a sentence exactly what you want to know here?  I have made a guess.   According to Wikipaedia, the average human female body weight is 45.5 kg (I'm not sure which women were weighed in order to come up with this figure, although they may well reference the research in the article) and the typical domestic cat weight is around 4-4.5 kg (the same goes for this one).  However, for both species, weight varies considerably between individuals, even those individuals of a healthy weight.  For instance, one woman might be at their perfect weight at 8 stone and another at 11 stone, because women are of different heights and different % muscle mass.  One cat may be at their perfect weight at 2.9kg and another, bigger cat, at twice that.  It will also change across the life-stages, especially youth and pregnancy.  However, using those 'average' figures from Wiki, they usefully divide so that an 'average' woman is about ten times the weight of an 'average' female cat.   Is that helpful?

Ps sorry reading that back, is wasnt meant to sound facetious - I wasn't sure if I was answering the question you were asking.  But if not please let me know and Ill try again.
