Verdict
Button batteries and AA/AAA cells both matter. A punctured cell leaks potassium hydroxide, which burns tissue on contact. Lodged button batteries can also generate current and perforate. Cats chew remotes, scales, and kids’ toys.
Symptoms to watch for
- • drooling
- • mouth pain
- • vomiting
- • refusal to eat
