I took my baby rabbit outside to play. i left her leash lightly tied around her neck because she chewed her harness and we haven't gotten one yet. I was watching my chicks when I heard her mae cute squeaky noises. I never heard her do that before. I thought her leash might be tight, so I took it off. Now I've noticed her breathing really fast and loud. Is somethng wrong? I took her to my mom, but she can't hear well and didn't notice anything.
