Hi
Though fairly new to SPF qigong (only about 40 days), I did do alot of healing work years ago and have been using qigong healing on my partner since I began. I've been going through the level 2 manual, as well as my impulses. I'd say, trust your instinct. Doing the small universe at the beginning and end as well as sword fingers, removing and giving healing is putting alot into your cat(or anyone). And if you feel moved to give more, do another complete session later. Also, every place you break up and remove blockages and then give healing is related to other channels, so all parts of the body benefit no matter where you are focussed. And that moment you are doning that could take 5 minutes or 20 or whatever. You could be moving very slowly. The most important thing I would imagine is your "intention" and directed focus and love for whoever you are working with. And most importantly, trust yourself! Don't get too caught up in protocol. Hope this helps. And hopefully someone whose been using the SPF qigong healing for longer can advise you.
