Common Health Issues in Rabbits
Rabbits are prey animals, which means they are masters at hiding signs of illness. This makes it incredibly important for owners to be vigilant and knowledgeable about the common health problems that can affect them. Many of these issues are emergencies that require immediate veterinary care.
1. Gastrointestinal (GI) Stasis
This is one of the most common and deadly conditions in pet rabbits. GI stasis is not a blockage; it is a severe slowing down or complete cessation of the digestive system. It can be triggered by pain, stress, dehydration, or an improper diet.
- Signs: This is a critical emergency. Signs include loss of appetite (refusing even favorite treats), small or no fecal pellets, lethargy, and a hunched posture indicating pain.
- Action: If you notice these signs, contact a rabbit-savvy veterinarian immediately. Treatment involves pain management, hydration, and medications to stimulate gut motility.
- Prevention: The key to prevention is a diet consisting of at least 80% high-quality grass hay (like timothy or orchard). Hay provides the essential fiber needed to keep the gut moving.

2. Dental Disease
Rabbit teeth grow continuously throughout their lives. A diet low in hay can lead to their teeth, including their molars (cheek teeth), becoming overgrown and forming painful spikes that cut into the tongue and cheeks. This is a very common and serious problem.
- Signs: Decreased appetite (especially for hay), drooling, weight loss, and facial abscesses.
- Prevention: An unlimited supply of grass hay is non-negotiable. The side-to-side grinding motion required to chew hay is what wears down the molars and keeps them healthy.

3. Uterine Adenocarcinoma
This is an extremely common cancer of the uterus in unspayed female rabbits. The incidence is estimated to be as high as 80% in some breeds over the age of 4 [1].
- Signs: Blood in the urine, lethargy, loss of appetite, or aggressive behavior.
- Prevention: This cancer is completely preventable by having your female rabbit spayed, ideally between 4-6 months of age.
4. Head Tilt (Torticollis)
A persistent head tilt in a rabbit is most often caused by an inner ear infection or a parasitic infection of the brain called Encephalitozoon cuniculi (E. cuniculi).
- Signs: A noticeable and persistent tilt of the head to one side. This can be accompanied by loss of balance, rolling, or circling.
- Management: This requires a veterinary diagnosis to determine the underlying cause. Treatment may involve long-term antibiotics for an ear infection or anti-parasitic medications for E. cuniculi, along with supportive care.
5. Respiratory Infections ("Snuffles")
"Snuffles" is a general term for an upper respiratory infection in rabbits, often caused by the bacteria Pasteurella multocida.
- Signs: White, snotty discharge from the nose, sneezing, and matted fur on the inside of the front paws (from wiping their nose).
- Management: While some infections can be cleared with antibiotics, many rabbits become chronic carriers. A clean, low-stress, well-ventilated environment is key to managing the condition.

Due to their delicate nature, all rabbit owners should have an established relationship with a veterinarian who has extensive experience with rabbit medicine.
