They come with me on adventures and are good company when I am alone and lonely. They introduce my grandkids to live animals and put up with being carried around by their necks (up to a certain age, and then all bets are off). They are litter mates, brother and sister, and thus are a comfort to each other, since there will be no kittens for them. They tell me when I am too tired to work any longer and boss me toward a chair to rest.
No, I am not the cat lady but I do love these two.
