  • It’s extremely important to contact your vet straight away if you notice your rabbit is eating less than normal.

Many different things could have caused your rabbit to lose their appetite. It would be impossible to list every possible cause, but the some of the most common include:

Dental problems - dental problems are painful and often cause a reduced appetite.

Stress - stress is a common cause of reduced appetite in rabbits and is often triggered by what seem like minor events to us, such as a change in housing, loud music, or a new pet joining the household.

Gut stasis/ileus - gut stasis (also called ileus), is when the guts slow down, or stop moving completely. Gut stasis can both cause, and be caused by a reduced appetite - meaning it can become a bit of a vicious cycle. Gut stasis is an emergency that can be fatal if it isn’t treated quickly.

Diet changes - changing your rabbits’ food suddenly is likely to cause them a level of stress, and could even stop them eating. It can also lead to stomach upsets or diarrhoea. If you need to change your rabbits’ diet, always transition them gradually over a couple of weeks.

Stomach ulcers - stomach ulcers are a common problem in rabbits, often brought on by stress. They are very painful and often cause a reduced appetite.

Urine infections - urine infections are painful and often cause your rabbit to eat less.

Respiratory infections - a respiratory infection can cause a rabbit to feel unwell and stop eating.

Once your vet knows why your rabbit has stopped eating, they will be able to create a long-term treatment plan.
