Caring for one abandon female with a RI was hard enough, I couldn't imagine doing it for 6 or 8!

And no I am not surprised someone gave them up like that. People do all kinds of weird things. It could be as simple as they thought they had enough time to get babies, or maybe even sell some of them, and then suddenly they were out of time.

Of course, there is even a tiny chance the person who left them the first time even stole them, and that is why they were left behind.

Regardless, I applaud the OP for their willingness to take on that many sick animals, expensive morphs or not.
