Behavioural problems in rabbits
Rabbits are natural prey animals and life in a family household can potentially be quite stressful for them. In the wild rabbits spend a large part of their time grazing. In a domestic home where high energy food is available rabbits have a lot of unexpected free time. It is important to ensure that rabbits have ways to occupy this time otherwise there is the potential that they will redirect their energies to unwanted behaviours.
Rabbits may become aggressive and to understand why you need to look at a rabbit's lifestyle and put yourself in the rabbit's position. Wild rabbits rank towards the bottom of the food chain as they are prey to many predators (including humans). This explains why they are always on their guard for the first sign of danger and can react adversely when threatened.
If you are worried about any aspect of your rabbit's behaviour you should contact your vet for advice. Many behavioural issues can be easily managed and all are most easily resolved if they are dealt with as soon as they arise. Many rabbits end up in rescue shelters due to undesirable behaviours and by the time the behaviour is well developed it may be intractable and these rabbits may never be rehomed.
