naw a 4yo would probably forget or not say anything if he thought hed be in trouble. at 4yo a kid doesnt think "oh mom and dad are looking for the cat. i know where it is!" they are thinking "well mom and dad know everything so if they think coyotes ate it, then thats what happened." also, im sure the family didnt realize for a couple days, maybe even weeks since it was outside and on a farm, that the cat was missing. by then the kid wouldve forgot hiding the cat.
