is neosporin harmful to cats
There are some differing opinions on this, but generally, it is not recommended for cats. In fact, it could be toxic and deadly for them. Thatâs because Neosporin contains an antioxidant called, Polymyxin B. This has been linked to anaphylaxis and death, although these extreme reactions are rare. Generally speaking, however, many vets and other health experts adamantly oppose the use of Polymyxin B on cats.
