Neosporin On Cats. Yes, it is ok to use neosporin on your dog with veterinarian approval, but we do not recommend using it on cats. Clean your cat's wound before breaking out the ointment, taking care to remove any dirt or debris around the injury.
It is not against the rules to apply neosporin to a cat’s bruise, but owners should proceed with caution. It is advisable to explore alternatives or consult your veterinarian rather than risking the life of your cat. Neosporin is not labeled for use in cats, so it is illegal to apply it to a cat.
