Just last month, my parents and I adopted a new bunny. She is only about a year old and she's our first bunny, so we don't know much about them or their behavior. Something that has me worried is, when I've held her before, she seems to either start hyperventilating immediately, or interchange between normal breaths and hard ones. Even when she appears to be relaxed, and/or sleepy. I'm concerned that she may be afraid or unhappy being held. Can anyone please help me?
