He's still sick, and they don't know what's wrong with him. They have to send away for bloodwork. The vet pushed, prodded, and poked around, and said Artoo's intestines could be blocked, but it was hard to tell. They wanted to make sure he doesn't have other stuff. They understood the payment problem (they have in the past), so they are only doing a little at a time. They gave him some antibiotics (he got a runny nose today), took blood and urine samples, gave him some saline solution and some pepsid for his stomach. He's home now, looking as sick as ever.
