[nagdu] Getting a urine sample

[Tracy Carcione]

I've been trying for the last 3 days to get a urine sample from Ben.  I'm
supposed to get the first donation of the morning, so I only get one
chance a day.  I've got the old pint take-out container, which is maybe 4
by 4 inches.  I've tried putting it off to the side, where I think he's
aiming, and I've tried putting it under his belly, closer to the source. 
I get a little in the bucket, (and some on my hand and coat), then Ben
stops.  "Yo, what are you doing?!  I'm trying to pee here!"
I don't know how much I really need to give the vet, but I'd imagine it's
more than the few drops I've managed so far.
If anyone has a good method, I'd sure like to know.
