Basics and possible causes
Seizures occur when there is abnormal and excessive neuronal activity in the brain. This activity leads to the motor, sensorySensory refers to the senses or perception. Sensory systems in dogs and cats include sight, hearing, smell, taste, and touch, all of which are central to interacting with their environment., and behavioral symptoms that can be observed during a seizure. The exact mechanisms that lead to seizures are complex and can be influenced by a variety of factors.
A common cause of seizures in cats is epilepsy, a neurological disorder characterized by recurrentRecurrent refers to a disease that repeatedly returns or worsens after a temporary remission or improvement. seizures. Epilepsy can be idiopathicIdiopathic refers to a condition or disease for which the cause is unknown. It is used when no clear external cause or underlying disease can be identified as an explanation for the symptoms., meaning the exact cause is unknown, or it can occur secondary to other conditions.
Other possible causes include infections such as FIP (FelineFeline refers to anything related to cats. The term is used to describe diseases, behaviors, or anatomical aspects that are specific to cats. InfectiousInfectious describes the ability of a pathogen to be transmitted from one individual to another and trigger an infection. It also refers to diseases caused by such pathogens. Peritonitis), toxoplasmosis, or rabies, which affect the central nervous systemThe CNS (central nervous system) consists of the brain and spinal cord.

MetabolicMetabolic refers to metabolism, i.e. the entirety of chemical processes that take place in a living organism to enable life processes. Metabolic disorders can cause a variety of Diseases in Dogs and cats. disorders such as hypoglycemiaHypoglycemia is a condition in which blood sugar levels fall below the normal range. Symptoms may include tremors, sweating, Hunger, confusion, and in severe cases, loss of consciousness.

It can be acute or chronic and requires immediate medical treatment. can also triggerA trigger is a stimulus that elicits a specific reaction or state. In veterinary medicine, this can refer to emotional responses, such as fear or aggression, or medical conditions, such as seizures in dogs and cats. seizures. In addition, brain traumaA trauma refers to a physical injury or damage caused by external force. Traumas can range from simple cuts to severe multiple injuries., tumors, or poisoning (e.g., from pesticidesPesticides are chemical or biological substances used to control pests, including insects, weeds, and fungi. In dogs and cats, exposure to certain pesticides can be harmful to health and lead to signs of poisoning., medications, or toxicToxic means "poisonous" and refers to substances that can have harmful effects on the body, including damage to organs, cells, or disruption of metabolic processes. plants) can also lead to seizures.
Genetic predispositions also play a role, as certain cat breeds may be more susceptible to seizures. Environmental factors such as stressStress refers to the state of an organism reacting to external stimuli or demands. In veterinary medicine, stress can have physical or psychological effects on animals, impacting their health and well-being. or sudden changes in daily routine can also act as triggers.
Typical accompanying symptoms
-
Behavioral changes: Before a seizure, cats may appear anxious or restless, withdraw, or be unusually clingy.
-
Muscle twitching: Slight twitching or trembling in individual muscle groups, mostly in the face or legs.
-
Stiffness or Seizures: During a seizure, all the muscles in the body can suddenly become stiff, leading to a complete loss of mobility.
-
Loss of consciousness: The cat may lose consciousness during a severe seizure and not respond to external stimuli.
-
Salivation: Excessive salivation may occur, often accompanied by chewing or smacking movements.
-
Uncontrolled movements: Paddling movements of the legs, often associated with involuntary urination or defecation.
-
Disorientation: After a seizure, cats may appear disoriented or confused and have difficulty moving or standing.
When to visit the vet?
A veterinarian should be consulted immediately if a cat experiences its first seizure, as the cause is unknown and should be urgently clarified. Immediate veterinary assistance is also required if the seizures occur frequently or last longer than five minutes.
RecurrentRecurrent refers to a disease that repeatedly returns or worsens after a temporary remission or improvement. seizures that occur several times a day should also be considered an emergency. In these cases, there is an increased risk of a condition known as status epilepticus, in which the seizures persist or recur at short intervals without the cat regaining consciousness in between.
In addition, a veterinarian should be consulted if the seizures are accompanied by other severe symptoms such as lethargy, vomiting, or sudden behavioral changes to ensure a comprehensive examination.
Symptom recognition for animal owners and veterinary diagnostic procedures
It is important for the pet owner to recognize the symptoms of a seizure in order to be able to act quickly. Watch out for unusual behavioral changes, muscle twitching, seizures, or other symptoms mentioned above. Keeping a seizure calendar, in which the frequency, duration, and type of seizures are noted, can provide the veterinarian with valuable information.
The veterinarian will take a comprehensive medical historyThe medical history is the systematic collection of a patient's medical history through questioning. It includes information about previous illnesses, treatments, allergies, and lifestyle habits. and may perform a series of diagnostic tests to determine the cause of the seizures. These include blood tests to rule out metabolicMetabolic refers to metabolism, i.e. the entirety of chemical processes that take place in a living organism to enable life processes. Metabolic disorders can cause a variety of Diseases in Dogs and cats. disorders, as well as imaging procedures such as X-rays or MRI to detect structural abnormalities in the brain.
An EEG (electroencephalogram) can be performed to monitor the electrical activity of the brain and detect epileptic activity. In some cases, a cerebrospinal fluidCerebrospinal fluid is a clear, colorless liquid that surrounds and protects the brain and spinal cord. It acts as a shock absorber and is involved in regulating the chemical environment of the CNS (central nervous system). examination may be necessary to check for the presence of infections or inflammatory conditions in the central nervous systemThe CNS (central nervous system) consists of the brain and spinal cord. It is responsible for processing information and controls most functions of the body and behavior..
What can pet owners do and professional therapy options
During a seizure, the pet owner should try to make the cat’s environment as safe as possible to avoid injury. Remove dangerous objects and pad the area if necessary.
Do not touch the cat directly during a seizure, as it may bite or scratch involuntarily. Stay close and observe the cat to record the duration and type of seizure.
After the seizure, the cat should be placed in a quiet, dark room to recover. Avoid loud noises or bright lights, as these could additionally stressStress refers to the state of an organism reacting to external stimuli or demands.

It is important to remain calm and, if possible, record a video of the seizure to show the veterinarian. This can help with the diagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients. and the decision about the appropriate treatment.
In the long term, the pet owner should carefully follow the veterinarian’s instructions for medication and management of the seizures. Regular check-ups and adjustments to the treatment may be necessary to optimally control the seizures and ensure the cat’s well-being.
Outlook on current research
Seizures in cats are a symptom that is receiving increasing attention in veterinary medicine, as it can be an indicationIndication refers to a valid reason or rationale for using a specific treatment, medication, or medical procedure. It is based on the diagnosis and the patient's clinical condition. of various neurological or systemic diseases. Current research focuses on better understanding the underlying mechanisms in order to develop effective treatment strategies. A key component of the research is genetic studies aimed at identifying specific genetic markers that could predispose cats to seizures. These studies could make it possible in the future to identify at-risk cats early and take preventive measures.
Another area of research concerns the improvement of diagnostic methods. Imaging techniques such as magnetic resonance imaging (MRI)Magnetic resonance imaging is an imaging technique that uses strong magnetic fields and radio waves to create detailed images of the inside of the body. It is used in veterinary medicine to diagnose diseases of the brain, spine, and other organs. and computerized electroencephalograms (EEGs) are being further developed to enable a more accurate diagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients. of neurological disorders. Researchers are also working on the development of non-invasive techniques that are less stressful for cats and still provide precise data.
Pharmacological research also plays a crucial role. Various drugs are currently being tested to evaluate their effectiveness in controlling seizures. New antiepileptic drugs are being developed and tested in clinical trials to determine which combinations are best suited for cats without causing significant side effects. This research aims to create tailored treatment plans based on the individual cat’s response to medication.
Behavioral research is another aspect that is being investigated. Researchers are analyzing how stressStress refers to the state of an organism reacting to external stimuli or demands. In veterinary medicine, stress can have physical or psychological effects on animals, impacting their health and well-being. and environmental factors can triggerA trigger is a stimulus that elicits a specific reaction or state.
