Hi, I took my 6 month old Neko to the vet today, and he was diagnosed with a mild ear inflammation. The vet prescribed an ear drop called Surolan, and applied it for him. It has been over an hour since we got home, and he is still constantly shaking his head and groom/scratch his ears. There is even a little bit of blood in one of his ears. His ears are also flatter than usual. Is this normal? The vet said some head shaking and flat ears are normal, but this seems like a bit too much?
