This November Cinnamon was surrendered by a guardian who loved her but was unable to continue to manage her medical condition, Encephalitozoon cuniculi (aka E. cuniculi, EC). Learn more about E. cuniculi, how to spot the signs, and how you can help bunnies like Cinnamon.

ℹ️ About E. cuniculi
EC is a parasitic infection in rabbits and other small animals. Whilst some rabbits are asymptomatic, in others the tiny parasites can attack the brain, nervous system, liver, kidneys, heart and lungs.
Many rabbits carry the parasite and it can lay dormant. Caught early, recovery can be possible with effective treatment, however nerve and tissue damage cannot be reversed if left to worsen.
🔎 Signs of EC can include:
- Head tilt to one side
- Leg paralysis or weakness
- Neurological problems, like seizures, eye tracking or behaviour changes.
- Excessive drinking or urination.
🙅♀️ How to prevent EC
Restrict exposure to unknown rabbits or areas that could have been exposed. New rabbits should be tested and treated before being introduced, and areas thoroughly cleaned and disinfected before you allow a rabbit to access them.
If you ever have any concerns, contact your veterinarian.
At just 1.5 years old, Cinnamon has a real lust for life and deserves the best chance of recovery, and we’re backing her every hop of the way to get there.
