Minecraft control for eating

What key will let me eat?! My food bar is down low, and I'm not regenerating health. I also need to know which button to press to hand bones to wolves, or fish to kitties.

It used to be the right-click button, but I'm not getting that option.

Solution 1:

While you hold the food in your hand, you must hold down the right mouse button until the food is gone. This takes somewhat between 1-2 seconds, and an eating noise will be played for the duration.

Edit: Right click at a dog to give it a bone if you have one in your hand, same with cats, just use a raw fish instead of bones.

Note: it will almost always take more than one bone/raw fish to tame an animal.

Solution 2:

You right click to eat. You need to hold down the right mouse button until the food disappears.
Note: When your hunger bar is almost full, your health will regenerate.

For feeding animals it is right click as well.
Note: It may take more than one bone or fish (wolves or ocelots) to befriend them.
