If your hamster has had a seizure, contact your vet and schedule a checkup right away. Only your veterinarian professional can diagnose a seizure in your hamster and recommend the best treatment plan. Seizures in hamsters are not common especially genetically. However, seizures can occur due to accidental ingested and inhaled toxins, brain injuries, injuries in general, or as a result of another illness. Treatment will be based on the cause of the seizure. Not a lot can be done for genetically caused seizures. Your vet may be able to prescribe a medication to keep your hamster comfortable and to make the occurrences of seizures less. If the seizure is toxin related then your hamster will need to detox. If the seizure happened because of an injury or an illness then the injury or illness will need to be treated in hopes that the seizures will subside.
