Hey so my bunny is a 1 year old male not neutered yet but he is grunting kind of, i dont know how to explain it but when he is running i can hear a very guiet grunt kind of like a pig or something i know it sounds stupid but i was wo dering if any other bunnies do this or if i should tske him to the vet, he has been dooing this for qukte a while, i just never thought anything about it but always best to be sure i guess.
