Seiko’s precious Siamese cat, Naya, suddenly began having strange facial twitching and drooling. Seiko takes Naya to see the veterinarian, who takes x-rays. The veterinarian explains to Seiko while they are taking the x-ray that it sounds as if Naya had a seizure. Once the x-ray is developed, the veterinarian shows Seiko a small tumor that seems to be putting pressure on Naya’s brain. This, the vet says, is most likely what caused the seizure. In Naya’s chart, what term will the veterinarian MOST likely use to describe Naya’s seizure?
