Aggressive rabbit body language includes a tense, low crouch with ears pinned back or upright and facing out, a raised tail, grunting, lunging, boxing (swatting with front paws), thumping, teeth showing, and potential biting or urine spraying as territorial warnings to stay away. These signs signal fear, irritation, or territoriality, indicating they feel threatened and may lash out.
Tense body, upright tail, laid back ears / Lunging: Lunging or a tense body with laid back ears and upright tail is an angry or territorial behavior. The rabbit is telling you it doesn't like what you are doing and is prepared to fight.
Rabbits grunting usually means they're angry and possibly feel threatened. Sometimes, the grunting is followed by a nip or bite. Some rabbits do not like it when you rearrange their cages as you clean. So they might grunt, charge, or even nip you when you try.
The 3-3-3 rule for rabbits (and other pets) is a guideline for adjusting to a new home: 3 Days for the rabbit to feel overwhelmed and hide, 3 Weeks to start settling in and showing personality, and 3 Months to feel truly at home and build a strong bond. It helps adopters manage expectations, understand that fear and skittishness are normal, and encourages patience as the bunny decompresses in its new environment, emphasizing providing a safe space and routine.
Understanding your rabbit's feelings
A good place to start is to look at your rabbit's ears. If they're close together, facing upwards and pointing outwards, your rabbit is likely to be relaxed and happy. If they're worried, their ears will be flattened against their back.
If they are sitting upright and their front paws are 'boxing' at you, they are likely very unhappy. Vocalising. Rabbits don't tend to make much noise and when they do it's a sign they're feeling very threatened. You may hear them grunting or growling and in extreme cases, they can scream.
Happy Trembles: The Good Vibrations
Just like how we might wiggle with excitement, rabbits can tremble when they're experiencing positive emotions. You might notice this happy trembling when: Your bunny is being petted in their favourite spot. They're exploring an exciting new toy.
Signs of a stressed rabbit include body language like ears pinned back, a tense hunched posture, wide eyes, and stillness, combined with behavioral changes such as hiding excessively, aggression (biting, lunging), destructive bar biting, changes in eating/toileting, restlessness, rapid breathing, or unusual vocalizations like grunting. These signals, often a prey animal's reaction to feeling threatened or unhappy, need prompt attention as chronic stress can cause serious health issues.
Rabbits are prey animals; that is, they are the ones preyed on by the carnivorous animals (raccoons, dogs, wolves, cats). Raccoons have been known to scare a rabbit to death just by crawling over his cage, never making contact. Your rabbit depends on you to keep him safe.
Take the bunnies for a car ride.
Take them out in separate carriers and then when you are in the car, put them together in a place where you can still get to both of them in case they do fight. You can use a laundry basket or a box. If the top comes off your carrier, you can also use that.
If your rabbit is being aggressive, but you are sure they are not in pain, ask yourself whether they might be afraid of being handled, and why. Are you suddenly appearing where they didn't expect you to be? Speak to them as you approach so as not to startle them. Always use a calm, quiet voice.
Signs and Symptoms of Aggression
The easiest way to tell which one of your rabbits is dominant is to watch their grooming. A dominant rabbit will groom the other rabbits far less and for shorter periods of time than the other animals. A dominant rabbit will often thrust their heads towards the other rabbits.
This behaviour often includes lunging, biting, or growling. On the other hand, unneutered male rabbits may show aggression due to competition-driven instincts like marking territory or seeking dominance, particularly if other rabbits are nearby.
Splooting is when a dog, cat, or rabbit lies flat on their belly with their back legs stretched out behind them — kind of like a superhero pose. It's their way of relaxing, cooling off, or just lounging in the most adorable way possible. Whether it's a full sploot or a lazy half-sploot, it's always a crowd-pleaser.
Behaviors such as grunting, nipping, boxing at you with their paws, and stomping are signs of aggression, which mean you should leave your bunny alone. A bunny stomp is very loud and obvious. If your bunny continues to stomp, check the surrounding area to make sure there is nothing making your bunny feel threatened.

Symptoms of stress
Rabbits are social animals and need attention and companionship to be happy and healthy. A lack of socialisation, changes in their environment or too much stimulation can all lead to stress in rabbits. In some cases, even the presence of other animals or humans can be stressful for rabbits if they are not used to them.
Rabbits will groom each other to show love and dominance If you see more than one rabbit living together, you might notice that they will often lick each other.
Solo rabbits will thump to express fear or seek attention from their human caregivers. In contrast, bonded pairs or groups of rabbits often rely on each other for cues about safety. If one rabbit thumps, their companion may follow suit as a shared response to potential danger.
