Cats are now the most common pet in the United States, with over 85 million owned cats reported in a recent survey. Approximately one third of U.S. households now have at least one cat living in them, and more than fifty percent of these homes have more than one kitty. Interest in and concern for non-domestic cats has also flourished in the form of support for conservation efforts that span the globe. Clearly, we love cats, and we are concerned for their welfare and happiness.
