**Ivermectin for Cats: A Comprehensive Guide**

Introduction

Ivermectin is a widely used antiparasitic medication that has been found to be effective in treating a variety of parasites in cats, including heartworms, ear mites, and roundworms. It is available in both oral and topical forms, and it is generally considered to be safe and effective for use in cats when used as directed.

How Does Ivermectin Work?

Ivermectin works by binding to glutamate-gated chloride channels in nerve and muscle cells. This action allows chloride to flow into the cells, which leads to hyperpolarization and paralysis of the parasite. Ivermectin is not effective against all parasites, and it is important to consult with a veterinarian before using it to treat a particular parasite infection.
