Strange as it may seem the way this thread has evolved, I do. My buyers and I sign copies of a sales agreement at the point they choose a specific kitten and before they hand over any deposit. The difference between my document and others I've seen is that mine stipulates MY responsibilities as well as the buyer's, exactly what I'm providing and their options and what happens over the return of any monies already paid if I cannot supply their chosen kitten. As I am happy to take cheques from buyers I've come to know over many weeks it also contains the statement that the kitten remains the property of the breeder until full payment has cleared. All the other stuff is in my care sheet.
