My cat Love is constantly scratching around her head and face. This has been going on for some time now. I have checked her and can't find a single flea or flea dirt. She also sleeps with me, is in on my bed close to 24/7 so you would think it if was fleas I would be feeling the effects by now? Getting bitten, seeing fleas on the bed, etc? My other two cats also occupy the bed, and they aren't scratching either. Could it be stress related? She is a Torti and tends to be high strung. Her brother Hershey also is a bit of meanie toward her at time which keeps her somewhat upset.
