Lead Poisoning by Porcelain Overglaze Color in a Cat and Dogs

Abstract

One cat (8-year-old) and two dogs (2-year-and 50-day-old) licking and swallowing porcelain overglaze colors attached to their haircoats and foot pad showed digestive and nervous symptoms and blood examination revealed blood lead concentrations as high as 54 (feline), 240 (canine case No.1) and 46 (canine case No.2) gg/dl, respectively. Radiography indicated lead lines (metaphyseal sclerosis) at the long bone metaphysis in a puppy (canine case No.2). By chelate therapy, the feline and canine No.2 cases recovered, while the canine case No.1 died after severe convulsion.
