When rabbits are very young, you can convince them to pose with guinea pigs, even nose to nose... and they won't complain. They haven't realized yet that there is a whole world to explore.
Although if he or she wants to eat some grass on the other side of the guinea pig, he or she may find it more convenient going over than around the aforementioned guinea pig.
However, a few days later, the baby bunny will have grown a lot and will realize posing for photographs, no matter how staged and cute, is less fun than climbing all over bedding.
Thanks a lot Nelson.
