My rescue cat has always been sort of aggressive, her rescue didnt really get her any type of evaluation to determine if there was any underlying issue causing her to have this aggression. So we kept her because I knew it would be difficult to adopt her out and I didnt want her going to petsmart for boarding, bounce around from home to home or worse be put down for behavior. This was over a year ago, she has since adjusted to our family, our pets and for the most part seems over all happy, Well last night she suddenly began to freak out, kept licking her lips excessively, her back along w her ear and paws were twitching. She would seem to be trying to catch something around her but there was nothing there, almost like hallucinations? She was running back n forth looking at her back, bottom, and she just looks stressed out. Her eating has slowed down as wekk as her water intake, she goes outside and doesnt want to come back in. I just feel her behavior changed almost over night. Ive made an appt w her vet and its scheduled for next week, in the mean time I did some online searching and it looks like all sgns point to hyperesthesia? It says it could be due to fleas , parasites amongst other things however she is on revolution she doesnt have worms, I even bought a flea comb just to see if maybe that was a possibility but theres nothing! Im concerned about her since she looks uncomfortable. Is there anything to do or give her till her appt to keep her calm and less uncomfortable
