"Out" ... when they are in a room that I am trying to keep them out of ... like my bedroom when my asthma is flaring up!

"Get Down" .... although they understand it, many of them toy with me until I get a few steps closer!

"Treats" .... I do believe they know this one too!

Every single one of them knows their own name without a doubt! I can call one of their names in a full room, and only that cat will respond!
