The most common reason rabbits suddenly become mean is because they hit puberty. Getting the rabbit spayed and neutered will typically fix their aggressive behavior. Other possible reasons for sudden aggression in rabbits include illness, territorial instincts, fear, partial blindness, and pregnancy.
A biting rabbit is usually a very scared rabbit, and this may be due to one of the following reasons: They have not bonded with you, either because they are new to the household, or this vital process has not been completed yet. Attempts to pick up your rabbit may lead to several loud thumps as a warning.
Always give a loud eeeeep whenever they bite you. This is how rabbits communicate to one another that they have been hurt. Follow quickly with a firm "No Bite!" Once the behavior has stopped, be as quick to offer praise and love to reinforce their good behavior.
Circling, mounting, and biting are classic signs of a sexually frustrated bunny. It may be cute at first, but it can develop into a pretty nasty habit. Neutering males and spaying females can dramatically reduce aggressive behavior.
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.
Your Rabbit May Be Showing You Love
Typically this isn't something you should worry about especially since it often doesn't hurt. Many times this is how your pet rabbit will show its love for you. When a rabbit nibbles or bites you softly it is often accompanied with licking, which is a sign of love.
Pay attention to the pecking order.
Give the dominant rabbit their treats first and give them their first choice of toys. You can provide equal treatment to the second rabbit, but you do want to pay attention to who gets stuff first.
Bunnies show affection by grooming, so if your rabbits gently nuzzle, lick, and perhaps even try to nibble you gently, they are showing you that they love and care for you. This is also a sign of submission. Sometimes your bunny will lick and nibble your clothing or a piece of nearby fabric instead of you.
The rabbit bites for affection and attention
Nibbling is a way of calling and attracting the attention of the pet parent. If the rabbit bites feet and hands, it means that he wants food and cuddles. The rabbit may also bite the cage to attract our attention.
This behavior is most often a fear response or the rabbit acting territorially. In both cases, the aggressive behavior should be dealt with. Otherwise, the rabbit may grow more defensive or experience unnecessary stress.
The best way to gain your rabbits' trust is by simply spending lots of time being near them, while allowing your bunnies to approach you in their own time. By sitting quietly with them in a safe enclosure, you'll show your rabbits that you aren't to be feared and that you can be trusted.
Use Vocal Discipline
If your rabbit bites you, a shrill squeal can be an effective deterrent, and clapping your hands or shouting are also good ways to get a bunny to stop the activity it is engaging in.
Petting a rabbit may be a great method to soothe them and help them relax. If your rabbit is defensive, scratch him behind the ears and forehead. Keep an eye on your rabbit's body language to see if he's still on the lookout for danger.
Generally, rabbits bite because they have a need to assert dominance, defend their food, or protect themselves from a predator. A dominant rabbit may bite an owner for no apparent reason. Indoor rabbits may suddenly nip at their owner's hands and/or feet when they move too close to the rabbit's territory.
Sit or lie down on the floor. If the floor won't work for you bring the rabbit up on the sofa or bed with you. Be Patient, don't rush. It can take a few months for a rabbit to adjust to a new home and new people.
Rabbit spritzer
You can use a plant spray/mist bottle to gently spray water on your rabbit's ears which can help them to cool down.
In the wild, rabbits would spend their time digging, running, jumping, rearing up, hiding, eating, socialising with other rabbits (and being alone sometimes too). To allow your pet rabbits to carry out their natural behaviours they need to be given plenty to do.
Your rabbit may learn to accept being picked up, but down deep inside, in the most ancient recesses of the rabbit brain, chemicals are being released that cause physical responses to danger. Your rabbit will learn to "ignore" these, but even the calmest bun is indeed having a physiological response to being picked up.
In general, rabbits do not like to be picked up. The act of bending over them and grabbing them by their ribs to pick them up is very similar to being picked up by a hawk – scary!! The best way to interact with your rabbit is on the floor.
Understanding your rabbit's feelings
If they're worried, their ears will be flattened against their back. You can also look at your rabbit's eyes and body posture, as well as their behaviour - for example, a rabbit may be anxious if they're hiding.
