Am I understanding right that the seizures started due to poison? So he might not have epilepsy at all? If he has been seizure free for months and he is only 10 months old, I would want to try to cut back his KBr and see if he remains seizure free. Maybe he is past that and recovering from his poisoning. Either way, remove as many chemicals from his environment as possible. These include air freshners, scented candles, cleaning agents, pesticides, herbicides, fertilizers, and any thing else you can think of.
