Hi, I'm a new member and am looking for some help. My six mo old cat just recently started itching. It seems to have gotten worse over the past few days. Her back starts twitching like crazy and then she tries to lick/bite herself. She'll run around like a crazy thing and she's now taken to hiding behind the couch, which she has NEVER done before. I've noticed her fur is a bit greasy and she's got bad breath as well (smells like her food). I just finished switching her over to Wellness Core Grain Free a week or so ago. I also feed her a 1/2 can of Fancy Feast pate (no fish flavors). I saw some stuff about FHS online, and I was wondering if this could be the issue? Or possibly a food allergy? Or even my e cig vapor (no nicotine)? I'm so worried about her. I have a vet appt Thurs afternoon, but maybe I should go sooner? Pls help, I'm so scared for her
