The application of ivermectin is capable of eliminating nematodes and mites in cats. Ivermectin for cats can be used as an internal dewormer against roundworms. This is in addition to functioning as treatment for diseases caused by mites, both inside the ears and on the skin. Ivermectin is often used, for example, to treat or deter mange caused by ear mites in cats. Its application for the treatment of infestations by external parasites (fleas and ticks) is controversial, therefore we recommend the use of other antiparasitics that eliminate and prevent these re-infestations.
