My cat has scabs all over the underneath of her chin and some around her neck, I have googled a little and looked on here It could be feline acne but from what I've seen the scabs would usually be black if that was the case? The ones on my cat aren't and she is white so I'm sure, she itches a lot and it seems to be very uncomfortable for her. There's 3 other cats in the house and they are fine. Any ideas??
