Bonita Boo was poisoned two months back (lizard or some toxin) and had severe seizures, liver enzymes off the charts and blind. She came thru and has some vision, is an indoor cat now and is happy. Suddenly she started having seizures. The vet said her blood work is fine. Could this be some residual thing? Should I put her on anti seizure meds? He is very vague and since we live in a Caribbean island it is hard to get beyond basic care. Thanks.
