Well, after I shot last night, he started running around and playing like a maniac around +3.5, so I took that as a good sign (can't afford to overtest, so I fought the urge). He did hit the food a bit off & on after that, so I think I may have overshot by a bit, will probably try a teeny bit less if I shoot again next week, but anytime recently I've shot 0.2u it's been pointless. Might try 0.3u, but hoping it won't be needed. His legs look WAY better today and he's back to jumping normally, so I *think* I did the right thing shooting. HAPPY NEW YEAR'S EVE everyone... can't believe it's here already, time really flies!!!!
