Understanding Cerebellar Degeneration in Cats
Cerebellar degeneration in cats refers to the progressive degeneration of the cerebellum, a part of the brain responsible for coordinating movement and maintaining balance. This condition can manifest in different forms and may have varying modes of inheritance.
Definition and Inheritance
Cerebellar degeneration can be of different clinical forms, with each form having its own characteristics and inheritance patterns. A study involving three cats spanning two generations concluded that cerebellar degeneration in cats can be of a new clinical form with an autosomal recessive mode of inheritance. Autosomal recessive inheritance means that both parents must carry a copy of the abnormal gene for it to be passed on to the offspring.
In some cases, cerebellar degeneration is described as a rare sporadic entity in cats (PubMed). This means that it occurs spontaneously and is not associated with a specific inheritance pattern. Late onset cerebellar degeneration is exceptionally uncommon in cats, with only a few reported cases (PubMed). The rarity of these cases makes them particularly noteworthy.
Clinical Form and Onset
Cerebellar degeneration can present in different clinical forms, each with its own set of symptoms and characteristics. The onset of symptoms can vary depending on the specific form of cerebellar degeneration.
Cerebellar hypoplasia is one form of cerebellar degeneration in cats. It is caused by the underdevelopment or destruction of the cerebellum, often due to infection with the feline parvovirus while the kitten is in the womb (WebMD). Symptoms of cerebellar hypoplasia typically become apparent when the kitten starts to stand or walk and may include jerky walking, swaying, hypermetria (overreaching), head tremors, and intention tremors.
Cerebellar abiotrophy is another form of cerebellar degeneration seen in cats, as well as in many dog breeds (VIN). Clinical signs of cerebellar abiotrophy can vary with the species and breed. The onset of symptoms can range from 7 to 13 years of age in Brittany spaniels, 9-16 weeks in Kerry Blue terriers, and 6-24 months in Gordon setters.
Understanding the different forms and onset of cerebellar degeneration in cats is essential for accurate diagnosis and appropriate management of this condition. In the following sections, we will explore specific types of cerebellar degeneration in cats, such as cerebellar hypoplasia and cerebellar abiotrophy, along with their causes, symptoms, diagnosis, and treatment options.
Cerebellar Hypoplasia in Cats
Cerebellar hypoplasia is a developmental condition in cats where the cerebellum, a part of the brain responsible for fine motor skills, balance, and coordination, fails to develop properly. It is most commonly caused by the infection of a pregnant cat with the feline panleukopenia virus, which crosses the placenta and infects the kittens in the womb, leading to the underdevelopment or destruction of the cerebellum (WebMD). The symptoms of cerebellar hypoplasia become apparent when a kitten first stands and begins to walk, usually at around 2 to 3 weeks of age. These symptoms are nonprogressive and may improve over time as the kitten learns to compensate with other senses like vision and proprioception.
Causes and Symptoms
The most common cause of cerebellar hypoplasia in cats is the infection of a pregnant cat with the feline panleukopenia virus, which attacks rapidly dividing cells during the perinatal period when the cerebellum is rapidly growing and developing (VCA Hospitals). Other causes may include exposure to toxins, malnutrition, or genetic factors, although these are less common.
The symptoms of cerebellar hypoplasia in cats are characteristic and become evident when the kitten starts to stand and walk. These symptoms include:
- Jerky walking and unsteady gait
- Swaying or wobbling while standing or walking
- Hypermetria (overreaching or undershooting of limbs)
- Head tremors
- Intention tremors (tremors that occur when attempting to perform a specific movement)
It’s important to note that the symptoms of cerebellar hypoplasia are nonprogressive, meaning they do not worsen over time. In fact, some kittens may show improvement as they learn to adapt and compensate for their condition (VCA Hospitals).
Diagnosis and Treatment
Diagnosing cerebellar hypoplasia in cats involves a thorough physical examination and a review of the kitten’s medical history. The characteristic symptoms observed during the examination, along with the history of infection or exposure during the perinatal period, can strongly suggest cerebellar hypoplasia. However, additional diagnostic tests, such as blood tests and imaging studies, may be conducted to rule out other potential causes of the symptoms.
As cerebellar hypoplasia is a congenital condition, there is no specific treatment to reverse or cure it. However, with supportive care and appropriate management, cats with cerebellar hypoplasia can lead happy lives. The focus of treatment is on providing a safe and enriched environment that minimizes the risk of injury and maximizes the cat’s quality of life.
Some strategies that can help cats with cerebellar hypoplasia include:
- Providing a safe and comfortable living space with minimal hazards and easy access to food, water, and litter boxes.
- Offering low-sided litter boxes to allow easy entry and exit.
- Using nonslip surfaces and padded areas to facilitate movement and prevent injuries.
- Providing interactive toys and environmental enrichment to stimulate the cat’s mind and encourage physical activity within their capabilities.
Regular veterinary check-ups are essential to monitor the cat’s overall health and address any specific concerns related to their condition. It’s important to remember that cats with cerebellar hypoplasia can live fulfilling lives with proper care and support from their human companions.

Cerebellar Abiotrophy in Cats
Cerebellar abiotrophy is a condition characterized by the degeneration of the cerebellum in cats. This condition is primarily linked to a genetic predisposition transmitted as an autosomal recessive trait. The exact cause of cerebellar abiotrophy is unknown, but it is believed to be associated with a genetic abnormality.
Genetic Predisposition
Cats with cerebellar abiotrophy have a genetic predisposition to the condition. It is transmitted as an autosomal recessive trait, meaning that both parents must carry the abnormal gene for their kittens to be affected by the condition. Siamese, Persian, and domestic shorthair cats may be more likely to be affected by cerebellar abiotrophy.
To prevent the passing on of this condition to future generations, it is recommended to spay or neuter cats with cerebellar abiotrophy early. Before breeding, it is advisable to consider genetic testing for breeds that are more prone to this condition, such as Siamese, Persian, and domestic shorthair cats (Wagwalking).
Diagnosis Challenges and Treatment Options
Diagnosing cerebellar abiotrophy in cats can be challenging. The condition is typically diagnosed based on clinical signs, medical history, and ruling out other possible causes of cerebellar dysfunction. The presence of cerebellar atrophy or degeneration on imaging studies, such as MRI or CT scans, can support the diagnosis.
Unfortunately, there is no cure for cerebellar abiotrophy in cats. Treatment options focus on managing the symptoms and providing supportive care. This may include physical therapy and exercises to improve coordination and balance. Additionally, ensuring a safe and enriched environment can help cats with cerebellar abiotrophy live a better quality of life.
It is important for cat owners to consult with a veterinarian experienced in neurology to develop an appropriate management plan for cats with cerebellar abiotrophy. Regular check-ups and monitoring of the cat’s condition are essential to address any changes or complications that may arise.
Understanding the genetic predisposition and the challenges associated with diagnosing and treating cerebellar abiotrophy can help cat owners provide the necessary care and support for their feline companions.
