Our guys got a new toy today and I tested him at +6 and he was 160 so I wasn't worried about a little exercise but... He freakin loves this toy and has been playing forever with it...running all over the place pouncing and attacking and flipping around... so I tested him an hour later and he only went down a smidge cause he's been eating plenty. I'm just wondering if you're already going lower at nadir and do a lot of rigorous exercise for 1.5-2 hours straight...am I playing with fire? I'm just so happy to see him so happy and himself. Does anyone do a lot of vigorous running around the house type exercise around nadir and had any issues?
