hamster urine should come out a bit like diluted bannana milkshake (sorry to put anyone off their drinks, but was the best I could think of!), but as said above, will go brown and sticky once it's started to dry, which might be when you're finding it. To be on the safe side, you might find it useful to put him in a plastic tub for a little bit until he wees, then you can compare the fresh stuff to what you've found and hopefully it'll look a little more healthy!
