Sometimes, after 3-6 month treatment, Neurological FIP cats might still have litte neuro symptoms. If you have such situation, it is not recommended to take higher dose Neurological FIP treatment for a long time.
Because a dosage is over 10 mg and longer duration of Neurological FIP treatment is not good for cat’s liver.
Some Neurological FIP issues maybe can’t be healed. Because the FIP did too much damage in the brain. Some of the cat owners can do with physiotherapy.
