No that looks like are Bob cats that we have down here , I really dont know if it was a lion or not . head stayed in line with body ,they way cats do when there focused on something ,grey colored ,long tail hung dow hind qaurters had that curve or hook in the end with black band. When it flicked its tail iside to side it was more the curve or bottom portion that it flicked around i. When it turned iaway it walked a few steps on the trail befor going into woods had what looked like muscular shoulders kinda rolled them side to side and had that paw ,paddle or flip cats do when they walk.
