[header] How to diagnose and treat hyperesthesia syndrome in cats [title] Monitor for episodes of abnormal movement. [step] Symptoms of feline hyperesthesia occur in short episodes of abnormal behavior. The cat will be doing something normal, like sleeping, sitting, or walking, and then suddenly they will start moving in a repeated, twitching way. 
These episodes generally last from around 10 seconds to a few minutes. [substeps] After the episode is over, the cat will go back to the normal behavior they were doing before.
