If a susceptible cat is born into or is entering an environment in which viral upper respiratory tract disease is endemic (e.g., some catteries, boarding facilities, shelters), the use of a topical product may be advantageous. Manufacturers are required by the US Department of Agriculture to establish, by means of experimental challenge exposure studies, the minimum duration of immunity for the rabies virus vaccines that they sell, and products approved for use every year or every 3 years are available. Vaccination may be considered for cats in multiple-cat environments, where infections associated with clinical disease have been confirmed. ./cache/cord-302247-moor7dfc.txt ./txt/cord-302247-moor7dfc.txt
