1. Medical Examination: Visit a qualified veterinarian to rule out any underlying health issues or physical pain that may be causing this sudden change in behavior. Rabbits can become aggressive when they are experiencing discomfort or illness.
Remember that rabbits are sensitive to various medications, so always administer them under the guidance of a veterinarian experienced in treating rabbits.
2. Stress and Fear: Rabbits are highly susceptible to stress and can become aggressive out of fear or perceived danger. Consider if any significant changes have occurred in the rabbit's environment or routine that may be causing anxiety.
3. Territory and Dominance: Rabbits are territorial animals, especially males. If multiple rabbits are kept together, there may be dominance struggles leading to aggression. Ensuring sufficient space and appropriately separating incompatible rabbits can help reduce aggression.
4. Hormonal Changes: Unspayed or unneutered rabbits can undergo hormonal fluctuations, which may contribute to aggression. Consider having your rabbit spayed or neutered if this might be the case.
5. Interaction and Handling: Rabbits have individual personalities and preferences regarding handling and interaction. Some rabbits may not enjoy being picked up, held, or cuddled excessively, and may express discomfort through aggressive behavior.
Always respect your rabbit's boundaries and avoid forcing unwanted interactions.
6. Consult a Specialist: If you cannot identify the cause of the aggression or cannot manage the situation on your own, consider consulting a behavioral specialist who can provide personalized guidance and techniques for modifying the unwanted behaviors.
Remember, sudden aggression in a tame rabbit is not typical behavior. Addressing any underlying medical or environmental issues while implementing appropriate behavioral modifications should help resolve the aggression.
