Anyway, Train is looking good. His face is still raw, but it's so much better than it was. Everyone is right, I guess. We'll see how he goes first. Although I think we're strongly leaning towards keeping him. That would probably mean we would have to move, but we were going to do that anyway. It's not such a great idea to live in housing attached to your company anyway, is it?
(I phoned the animal shelter (ARK) and when they told me they had someone in [the city where I work, two main stops away on the nearest train line], I was relieved. Then I asked them directly if it was likely they would euthanise the cat and their answer wasn't good enough. I said I couldn't let them take him in that case. The women got all passive-aggressive on me and asked me just what exactly I was planning to do and how would I ever pay for it. I guess, whatever I do, I won't be going through them.)
Anyway, regarding the water, I went back to the vet the next day. I bought two packages of cat food and they gave me medicine free of charge. I've got eye ointment which is applied morning and night, flea powder that is rubbed in once a day and antibiotics that are put in his food once a day. I suspect this is only going to get more expensive though. ^^ They told me that it was special cat food and there was enough water in it. I completely forgot to ask whether Train was male or female though -- we call him 'he', but we don't actually know!
Oh, and in case anyone was wondering, Train is indeed a Black Cat. :P
