When I need to thaw faster, I put the serving size I want in a plastic Ziploc bag, seal it well, and immerse it in almost-hot water in the sink.
When they get a food they aren't too interested in eating, I sprinkle freeze-dried-chicken crumbs on it (my two love freeze-dried chicken and there are always tiny crumbs on the bottom of the bag).
Others have suggested the water from a can of tuna (Make sure the only ingredients are tuna and water...drain the water and dilute it with their regular water).
