Causes of a reduced appetite
Dental problems are very painful, overgrown teeth can stop your rabbit eating. Rabbits need to eat a high fibre diet (90% grass and hay) to keep their teeth at the correct length.
A very high fibre diet is essential to keep your rabbits gut working properly. If they don’t get enough fibre, their digestive system slows down and this makes them feel poorly. Eventually this can cause the guts to stop working completely (gut stasis). This is an emergency situation that can be fatal.
Rabbits don’t cope well with sudden changes to their diet and it can cause them to stop eating. Any changes in a rabbit’s diet should happen gradually.
Changes in housing and stressful situations can stop a rabbit eating. Once they stop eating, their gut slows down and it can be hard to get it going again without veterinary treatment.
Stomach ulcers are painful patches that form in the lining of the stomach, this is a common problem in rabbits. Stomach ulcers are often caused by stress.
Diseases such as pasteurellosis (a bacteria) and myxomatosis (a virus preventable by vaccination) could make your rabbit feel unwell and stop eating.
Poisons and toxins
Poisonous plants like any plants that grow from bulbs, potato tops and oak leaves can cause serious illness.
Some medications can reduce a rabbit’s appetite. Speak to your vet if they have been prescribed medication and your rabbit seems to have stopped eating.
Lung disease, heart disease, kidney disease, gut blockages and tumours can all cause a decreased appetite.
