My Maine Coon Brian rounded up a bunch of escaped chicks once and herded them back towards their pen.
I love Maine Coons !!!! I met one only once and I thought it was the coolest cat I have ever seen. He acted like a big old friendly dog....
Not a “saving a baby” story but I have one that starts meowing loudly when my blood sugar gets low and won’t stop until someone does something about it. It has woke me up several times when I had fallen asleep so yes cats can and do save people. :)
