This seems like a bizarre symptom, but I read it on a symptom list the other day and can’t remember what it was for. When I got back, my cat had developed this symptom. For at least 24 hours, the fur down her back is standing straight up as though there’s static electricity caught in it, though there’s not, and it’s very oily looking only in that area.
Any idea what this could be? I think I was going down a list of malabsorption illnesses at the time I found it, but I can’t remember clearly.
