What does it mean when....

What in the world does it mean when your cat grooms you?? Or as Ive recently discovered GiGi likes to do...nurse on you. She actually tried to latch onto my neck..MAN THAT HURT!!!! But Im curious because she loves to groom and suckle on me especially but sometimes she will do it to BF....Hmmm any opinion!?!

She sees you as another big, friendly cats of sorts. She really wants to be pal with you both

Most times it is a case of true affection sometimes its about the smell. If you have a certain smell say from a perfume/lotion some cats find it curious and like to suckle.
