Hi,
You would know that best, as you are around your cat, and sense his/her state of being. If that doesn't work for you, try three focused sessions, either morning , noon, and night, or, three days in a row at noon. See how your cat does over the following week. Repeat if necessary, or 'periodically', if your cat seems fine. Maybe follow a bigger cycle of once a month or something, if things go well...
love,
gallen
