Ear Mites are a common parasite affecting cats that can be identified by the presence of a black waxy material inside the outer ear canal.  Ilium Ear Drops or Advocate can be used to kill this tiny mite which can cause your cat to scratch at its ears. From time to time some cats may suffer from weeping eyes or tear staining. Products such as Tear Stain Remover and eye wipes are great way to keep your cats eyes healthy and reduce discolouration.
