If the rabbits are kept apart and one comes back with a different smell or a change in health, they may reject each other and begin fighting. If this happens the introduction process will need to be carried out again.
If your rabbits are having trouble getting along, pet them together for 10-15 minutes at a time. It's also a good idea to end each bonding session with 5-10 minutes of head scratches and petting side-by-side to make sure you end on a positive note.
It's important that rabbits live with at least one other rabbit at all times, so that they feel safe. As they're social animals, they also enjoy eating together, grooming each other and lying down together to keep each other warm. Living together will also make sure that they have companionship.
It usually takes between two weeks and two months to bond a pair of rabbits. The process should always take place in a neutral territory and all rabbits involved should already be spayed or neutered.
Have hiding places and toys ready to put in the area, but leave it empty for when you first introduce them. Once the rabbits are comfortable with the sight and smell of each other, they can be introduced for short periods in the neutral area.
If your rabbits are mounting each other a lot, instigating fights, stop them, place them side by side. Pet them together and talk to them quietly. Do not let much chasing ensue. If they are persistently aggressive, separate them to prevent injuries.
It can take a few weeks to a few months to combine two rabbits into a "bonded" pair.
Chasing is a normal behavior to expect during bonding that you should allow to continue. This is not a true fight where the rabbits are getting territorial with each other. However, it can look similar to other behaviors that are aggressive.
Put the rabbits in nearby enclosures, where they can sniff each other through the wire. If your existing rabbit is free range, put the new rabbit in a small separated area so they can get used to each other's scent. You can swap around their litter trays and rub a cloth over each transferring scents.
Make sure to spend some time with the rabbits in one or more neutral space every day. When you're not actively working with them, they should be apart if they fight when together. If they do not fight, then they can be left alone if you're not working with them, but not when you're not home at all.
Rabbits can live alone, but you'll need to provide your pet with the attention (company, petting, grooming, exercise, playing, and enrichment) that a bonded rabbit partner would provide. It's always advisable to keep rabbits in pairs.
Rabbits can also exhibit distress at separation. As with dogs, symptoms include destructive behaviours such as chewing on slippers and carpets and reverting to unsavoury toilet habits. In many cases the remedy is broadly the same: a softly, softly approach to separation, building up steadily each day.
It's never too late to get a friend for your existing rabbit. There are many cases where older bunnies have spent their twilight years happily with a new companion.
Never have traditional stress bonding sessions for more than 10-15 minutes. By limiting the amount of time, your rabbits are acutely stressed, you can limit any negative health outcomes. Follow stress bonding with a cool-down period. After the 10-15 minute period, give your rabbits a chance to recover.
Even if you have a pair of rabbits, 24 hours is the maximum time they should be alone. Like all pets, rabbits rely heavily on their owners. Domesticated rabbits lack the survival skills of wild rabbits. Your rabbit has basic needs surrounding food, exercise, and stimulation.
Squeal. If your rabbit nips or bites you (sometimes rabbits nip when they want something or want your attention - it's not always aggressive): give a high-pitched squeal as soon as she nips or bites you. This will let her know that she hurt you and she should not nip or bite you.
When there is more than one rabbit, they may pull at each other's fur because of dominance or boredom. Often the dominant animal will pull the fur off the submissive animal.
Like many other animals, rabbits often nip and play fight as part of their bonding. Nipping is also linked to mating. Even a neutered male may nip and mount another rabbit – male or female. This is an act of dominance, not lust.
Barring the odd rogue rabbit that likes the lonely life, rabbits generally benefit from the company of other rabbits. They will often be far happier and content with a mate. Rabbits are not that unlike humans, they also get bored, even depressed, and when they do, they often act it out with destructive behaviour.
They must be neutered to prevent hormones from damaging their relationship. Never keep two unneutered male rabbits together, even if they're brothers. They will fight to the point of causing injury.
Often you can stop a fight before it begins, by separating or distracting your rabbits at the first sign of trouble. If a fight occurs during or shortly after the bonding process, you may need to start over from scratch. If your bonded rabbits are fighting, you may need to bond them a second time.
5. They are lonely. Because rabbits are social animals, they will often get depressed if they are left alone for too long. A rabbit who is treated like a cage animal and left alone inside their enclosure day in and day out is very likely to become lonely and depressed.
