Gave HTML ids to the meow and hiss links, added JQuery to preventDefault and stopPropagation of those links, and set request type, url and data type of the AJAX request.
Added respond_to blocks to handle json requests by rendering an instance of Meow, or an error message.
Changed the event handlers for the Meow and Hiss links to target the parent div of class meow which surrounds the actual Meow and Hiss links.  This prevents the event handlers from losing functionality when either of those links is replaced during an AJAX call.
Updated the JSON rendered by the meows controller when the #create action is used.  Now the meow JSON object includes its associated post. This allows the JQuery function updating the meow_count on the page to function properly.
