Rabbits love it when you pet them on their cheeks and foreheads.
When you pet the rabbit on it's cheeks or forehead the rabbit will put it's head on the ground and they'll close their eyes in contentment as you pet them.
Another thing rabbits really love is to be scratched on their shoulders and on their backs.
Rabbits typically don't love being touched on the feet, tail, stomach, neck or even ears.
