When my cat kneads my tummy, as they do, she not only goes into a kind of purring trance, but something wet and cold drops from the front of her face, possibly her nose. I'd assume it was 'snot' but it's freezing cold. Does anyone have any light to shed on this? I'm not worried, she's always done it, but I'm curious.
Here's a picture of her just to coax you all along - 13 year old rescue cat
