Provides an exemption for drugs and medicines for companion and farm animals

This bill creates a tax exemption for drugs and medicines used to treat illnesses in companion animals (like pets) and farm animals (such as cows or chickens), as defined by New York's agriculture law. It allows local governments (cities, counties, school districts) to choose whether to include this exemption in their local tax policies through ordinances or resolutions. The exemption applies to veterinary medicines and related medical supplies, but localities must actively adopt it - they are not required to implement it. This change modifies existing tax law to add this specific exemption to the list of optional tax breaks local areas can offer.
