I don't have much to add other than I'm glad to hear that others have had good luck treating this condition. Our shelter currently has a cat that I believe has this condition. He is staying at a wonerdful vets office. They are taking awsome care of him, and have found that if they distract him and keep him mentally stimulated he has fewer "episodes". His episodes were horrible & absolutely heart breaking. He would chase his tail bite it and scream. He is going to a nurologist on Thursday & I am hopefull that we will be able to help him. He is a sweet cat, that has had a horrible life (he has been abused on multiple occasions by children), and deserves to be happy.
