Missing small female black cat from Dublin 8

Cracker is a small black female cat. She is neutered. She is wearing a purple collar with a black tag with her name and my number on it. She is nearly two years old. She has small white patches under her front legs. She is house trained, but doesn't like to be cooped up all day. She is best friends with our two dogs, but is wary of other dogs. We miss her loads.
