My dads cat gets like this. She has more of it though and if you let it go she starts looking a lot like an alley cat in general. She is also a torti, his vet says he see''s is most in them. Sometimes allergy, otherwise just high strung/stressed. I dont know what he gives her though. My dad dont always keep up on her meds. If he dont take her in and she gets a mess she gets a shot (I assume steroid) She takes pills, 1/4 pill a day and keeps her just fine. I been meaning to look at the pills and see what they are but never remember. She has been this way for about 2yrs now.
