HI i had sort of the same trouble when i got my female cat ,she sort of made a snorting kind of noise when she ate and affectionate forget that ,oh unless your male (tart that she is ) but now days and shes only just 2 yrs she is mummys fatty she only comes to me now in the mornings and gives me loves and kisses but when shes had enough she had enough and she will let you know she just switches shes very fluffy and you cant see the claws but you do get the look to warn you , but in general female cats are not over friendly only when they want to be ,know as for male cats well there just soppy my one is ,dont worry about her not being happy of course she is and she'll come round in time ,oh yer when my female cat was a kitten if she got angry and went to claw me i would tell her of in a different tone of voice and it works cause when she is being naughty Quite often beating the male up cause he might of sniffed her i just change my tone and she walks of saulking, Be patient
