It was my fault.  I didn't make sure she was in last night.  Forgot, tho they usually ask to come in.   Coleman found her remains on the lawn.  A monster (predator).  The kittens are weaned but now they have no mother.  I always wanted to get a picture of all of them, but too late.  Sorry for the sad post.  The kittens seem fine though and they still have dad.  I have a picture of Jack and Diane somewhere and will post it when I find it.

We think it may be a big cat (scarey). But we also have coyotes, and other nocturnal predators.
