Re" Crosscat

as follows (cross and cat): 'Cross your heart and hope to die, And hope the cat'll spit in your eye." From 2107 Curious Word Origins, Sayings & Expressions from White Elephants to Song and Dance by Charles Earle Funk

and if not, do you know any alternative meanings because I have not been able to find the expression in any dictionary.

Perhaps I'm the only one who has not heard the word "crosscat." Is there such a word? Could you give it a little context, say, use it in a sentence or say where you found it? SS
