My cat has been leaving white stuff behind?

I have a male applehead siamese cat and lately when he lays down somewhere, we find white stuff where he was laying. It's not like dandruff, it's more like a liquid I think. But everytime we see it, it looks just like a dried out liquid instead of flakey like dandruff. And it's not like it came from his whole body, just one particular spot. I haven't noticed anything different about my cats appearance or behavior.
