I tried this new spread on friend's dog... the first 2 cards gave sensible answers (1 was IX of Swords, 2 was Page of Wands) but the final two (reversed Knight of Wands, reversed Knight of Swords) didn't make as much sense. Other ways to interpret this -- either the cards or the meaning of the place in the spread?
I tried redoing the spread and got reversed Fool, Strength, reversed Moon, and reversed Tower the next time.
I do kind of think my friend may be right in her theory that someone has taken the dog in, and either doesn't want to give him back or otherwise doesn't seem to know he's being looked for... the second places getting Page of Wands and then the Strength (with its picture in the RW deck of a girl taking care of a lion) suggest that.
Oh, and the 5th card -- got Ace of Wands and The Lovers, respectively
