i think to remember it said in the introduction thingy something about "5 free feeds" maybe thats where it came from. no biggie tho, however the original question is about different mounts on different heroes and no i would not think that will happen. look at it as some sort of a "bus" for your party. that bus got a top speed and gives you additional protection in form of HP. so i'd suggest to continue feeding the bear and ignore the leopard. however if you are low and rather new to the game, you may want to consider in cutting a little back on the feeding and rather invest your precious coins into runes and fair after you reached the 2nd star on your bear because your runes are much more important than throwing 5m a day into your pet for over a week to gain 5k HP.
