All of you have given me so much good advice! I really appreciate it!

Those parrot bowls definitely look handy! I'll have to keep my eyes peeled for some. In the meantime, I just refilled the water bowl by poking a sports bottle between the bars and squirting water into the bowl. It worked, but my being that close to the cage sure didn't do anything to help Mowgli's nerves (of course, neither will going to the vet tomorrow).

The next challenge will be figuring out how to get him out of the cage, into the laundry bag, and then into the carrier.
