The first step would be to confirm the diagnosis. Treating something you think it is without knowing for sure could cause more problems. I think your best option is to confirm the diagnosis and partner with a holistic vet for treatment. This is coming from someone who uses CDB oil for arthritis in her cat. So I really have nothing against holistic or alternative treatments, but you have to know you are treating the right problem first. Before starting my boy on CBD oil I had x-rays done and a specialist review them to confirm my boy really did have arthritis.
I don't believe there is a way to truly diagnose hyperesthesia - it is a matter of ruling out other possible issues, such as hyperthyroidism or some form of dermatitis. And, then, depending on the severity of the hyperesthesia no treatment may be needed. If the only sign is rolling skin and none of the other typical symptoms (fixation and obsession with their tail, chasing, biting, and twitching it very frequently, for example) exist, there is probably no reason to want to treat it. And, generally treatment doesn't go much beyond creating a stress-free environment and increasing exercise.
Hyperesthesia symptoms can also be more extreme, such as hyperactive and moody behavior, possible hallucinations, dilated pupils, and loud meowing for long periods of time. In these cases, anti-anxiety meds might be prescribed.
Natural remedies that I have heard of are: Spirit Essences (Jackson Galaxy) to help alleviate stressors that could trigger episodes; homeopathic treatments like Aconitum or Hypericum; and, I have even read about people who have used acupuncture, chiropractic care, and/or massage therapies.
Feeby exhibits some signs of hyperesthesia, but mostly skin rolling - so I decided not to try to treat it. For whatever reason, it seems to have lessened as she ages. Maybe because the environment in our house is pretty quiet and very routine.
My girl has mild hyperesthesia (she's only had a couple more serious episodes that I've witnessed). Her treatment includes CBD oil in her meals daily and cold laser therapy sessions every 2–3 weeks. I do the best I can to create a stimulating environment for her.
Recently, after doing some thorough reading, I started using litterbox technique, diffusion, and occasional topical application of AnimalEO. Cat Recommendations
Also, I read somewhere about "retraining" the nerves (?) by petting/rubbing the fur in the opposite direction of hair growth. I'm willing to try anything, so when she allows me, I rub the fur on her back this way (not more than once a day).
