If your pet has seizures, ask your vet to test him/her for food allergies. One of my dogs began to have seizures shortly after I brought him home from the shelter. I had my veterinarian perform a comprehensive allergy test (using a blood sample) and discovered that he had many allergies, including chicken and rice, which were both in the food that he was eating.
The company that provided the results from the allergy test also provided a list of foods (canned and dry) and treats that he would be able to eat safely. I switched his food to one of those on the list and he hasn't had another seizure. Food allergies may not always be the cause of seizures, but it is worth investigating with your veterinarian.
