I have a three month old holland lop female that used to be so sweet but I've noticed the past week or so she has suddenly become super skittish and anytime I put my hands into the cage to refill her food dish or give her more hay or veggies, will make this loud grunting noise and lunge at me as if shes going to bite. I dont know where this is coming from, she has free run of the room for at least 5/6 hours a day. Shes always been spoiled with tons of veggies/hay and has never had anything done to her that could have scared or hurt her. Ive had male rabbits in the past that were always so calm and happy so maybe this is normal for females? Help.
