Here's what I would do: Get a couple of carriers, put Mama in one and the babies in another and get them to a vet. I'm fairly confident that, if Mama led you to her babies, she'll be compliant. If you can't get Mama, get those babies. Even if all you can do is get them vet care and later have them altered, to be released again, you'll have prevented scores of future problems. And by all means, when you do get ahold of Mama, have her spayed. The goopy eyes are probably easy enough to treat but Mama shouldn't be allowed to keep having babies. I know it's easy for me to tell you what to do, sitting here at my computer while you're there in Germany in a quandary. I would venture to say, however, that most of us PTers have been in this situation more times than we can count. Good luck!
