They were; three of them were female (one solid black, one silver tabby point, and a torbie) and the fourth was a male orange tabby. We kept the torbie.
So I take it you noticed the notch in her left ear then?
Oh yes, I noticed the notch. Was it from a fight or was it a notch put there by a feral cat rescue group? Since she was pregnant, I tend to think it was a natural notch, as I think the notches the groups put there are to indicate the animal was spayed or neutered.
