I've always imagined Tara living in more urban surroundings, rather than the house she originally lives in (which looks like it belongs to an old lady with no sense of style whatsoever). So she and her kitties now live in 33 Mendoza Lane, Downtown.
The last room is sort of a spare room with only cat stuff (and plants) for now. Hopefully Tara won't end up the crazy cat lady whose only family are her cats for the rest of her life... in other words, this might eventually become a nursery. Or something.
