The back feet are to sit flat on the table and the front feet line up to the eyes with the head down.
What I do is do the back the strech out the front as far as the bun can go to make them long this is my daughters buck.
Try turning him the other way so you have more room to set him up. His front feet should be visible andflat on the table, like the rabbits in the pictures further up are. His rear end looks like its sticking up some so I'm thinking he doesn't have his back feet flat on the table either.
