Rabbits can show affection towards humans in various ways, such as by licking, nuzzling, and even gently nibbling. They may also enjoy being petted or cuddled by their human companions. Additionally, rabbits may demonstrate their affection by following their owners around, or even "binkying," which is a joyful jump and twist in the air. It's important to note that each rabbit has its own unique way of showing affection, so it's essential to pay attention to your rabbit's behavior and body language to understand how they express their love towards you.
