Need a Barn Cat or three?

Elmer, Emily and Elizabeth are about 2 years old and were caught with their mother when they were still babies. Despite our best attempts, they are very feral so are not really adoptable as pets, but, if their mother is any indication, they will be champion mousers! Their mama is living at a stable and the owners are thrilled with her talents. Not sure if this is Elmer or Emily and I haven't managed to get a good shot of Elizabeth who's a solid black beauty. All three are spayed/neutered and have 3 year rabies shots.
