You document everything.

The skinniness, the lack of feed. All of it.

It's a PITA, but it's gotta be done to save them.

Keep a log, every time you look at them, and record your findings.

Take pictures as often as you can think of, and upload them onto your computer.

4 to 6 months of documentation ought to be plenty.

It's a bummer that that is what it takes, but that's our humane society and sheriff department hard at work. :rolleyes
