I can't tell you how much or what to give your kitty. It sounds like your are doing good things. Where did you get this information? That source should tell you how much.
I would call Winterhawk, an animal communicator I have worked with. She can advise you on what to give by asking the kitty herself, and adding her experise. I have worked with her with very good results.
(707) 583-2348. She works over the phone and does not charge much. Tell her Ms. Kitty and Baka sent you.....
