Once the rabbits have bonded they should not be separated as this will cause significant distress and can severely damage the bond. Therefore, if one of bonded pair of rabbits needs to visit a vet, then both should be taken, which will provide comfort for them both.
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.
Rabbits are social animals, so a single rabbit is likely to feel lonely and depressed. 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.
Once the rabbits have bonded, DO NOT separate them. If one rabbit needs to go to the vet, both need to go. If they're separated and one rabbit comes back with a different smell or change in health, they may reject each other and begin fighting.
Stress can kill rabbits. When a rabbit is bonded to another rabbit and that rabbit dies or is removed it can cause stress on its bond mate(and itself). (Source) This stress could be enough to cause several problems that if not treated lead to death. Many rabbits respond to stress in different ways.
For bonded rabbits, the loss of a partner can be very traumatic. Bonded rabbits live very closely together, spending hours sleeping, grooming, eating, playing and "talking" so the sudden absence of their partner is difficult for them to cope with.
Rabbits are happiest living in pairs. While they love and enjoy human companionship, there are certain social needs that even the most loving pet parents can never completely fulfil. Rabbits living in bonded pairs are generally healthier than singly kept rabbits.
In general, rabbits will be happier in pairs than when they are single. A second rabbit can prevent depression, and even help to minimize boredom and troublemaking behaviors. However, enough social interaction from humans or other pets is also okay if getting a second rabbit is not possible.
Although trying to bond rabbits will inevitably be stressful to them, there are other factors that cause stress too and every rabbit owner should be aware of them.
In the wild, rabbits live in big groups and they enjoy being with friends who will play with them, groom them, understand them and look out for them. So if these sociable animals are kept on their own, they may become bored, depressed, and very lonely.
A lonely rabbit may become hyperactive and angry. They may display destructive behaviour such as gnawing at the carpets and other furniture. Lonely rabbits may pull at their fur and overeat.
In general, the only time you should give up on bonding rabbits is when they have injured each other. You should also reevaluate the bond if one rabbit is a bully, making the other rabbit anxious and afraid to eat, use the litter box, or even move around too much.
As a general rule, rabbits are bonded once they can spend 48 hours together without any chasing or aggressive behaviors. You also want to see positive signs such as grooming, sharing food, and sleeping next to each other to confirm that your rabbits feel safe around each other.
Bonded rabbits spend the majority of their days and nights together. They tend to visit the litter tray at the same time, eat together and groom together. A lot of time is spent simply snuggled up together sleeping. They can become competitive with each other over food and attention from us.
Your rabbits will still want to be with you and show affection, but will not be so clingy when it has another bunny friend. Bonded rabbits also bring their own advantages to rabbit owners.
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.
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.
Bonded rabbits will use the same litter box without fighting – make sure you have one big enough for both with space to move around. The litter box is like the sandbox in elementary school.
If you have a pair of bunnies sharing the same litter box, you'll want to get one very large box, or give the bunnies multiple boxes to keep them well supplied with hay and fresh litter. We recommend using CareFresh and fresh hay to prepare your bunny's litter box.
Nipping will most likely happen at some point during the bonding process. It is normal and isn't always a negative action. Sometimes a rabbit will nip the other because they want him/her to groom them.
Rabbits form a bond for life. Once the rabbits have bonded they should not be separated, as this would cause a great deal of psychological trauma to them both. It is recommended that both rabbits are taken to the veterinarian if one needs to attend.
When one cat in a bonded pair dies, monitor your other cat closely. He must eat, drink and use his litter box as usual. If your grieving cat stops eating for more than 24 hours, seek help from his veterinarian. Watch his sleeping patterns as well.
A broken bond
Bonded rabbits usually get on well over long periods of time. It's not uncommon for rabbits to occasionally scuffle, even in bonded pairs, but if they are having proper fights and pulling fur out that's usually a sign that their bond has broken.
