Male leopards do have a greater disparity in size. I think of it as
cheetah can only be so large to do what they do successfully. This
would tend to keep both female and male weights down if the theory is
correct. Leopards operate differently. I don't know why male
leopards are so much larger unless it is male-male competition and
testosterone. I'll have to find out. >

The figures I remember are 40% for leopard/lion and 70% for
dog/cheetah. But you're right. Cheetah lose a lot of kills
which does bring the number down.

I don't know. Maybe the experts have some ideas. I would like to
hear their speculation, too. I really was intrigued by the dino
climbing the tree with prey. Wish I had thought of it, even if it's
