Might be a Carolina Wren? However, I never thought of the call as "kitty, kitty, kitty". To me it sounds more like "tea kettle, tea kettle, tea kettle." The Carolina Wren also has a distinct alarm call that can alert the attentive listener when something is moving through, such as a deer.
a cardinal (red bird). This time of year the males are trying to win a mate. To me it sounds like "pretty, pretty, pretty" but I'd bet that's what it is. They are also, for some reason, one of the first birds up and singing every morning.
