If you look at my avatar at the left, she is the 2nd cat (first is black, then Millie is 2nd) - I think she's definitely a calico But you're right, she's a big girl! Her mama went off into the woods at the farm Millie was born at and has not come back (as far as I know of), but I was told that she is a very large cat, so maybe Millie is following in her footsteps.
