I am so sorry. At the very least, it sounded as though you have more than one kitty? Hold onto that remaining one and try to know your daughter will care for the other one very well. It can be so hard to not be selfish with innocent animals, but knowing it's taken care of is so much better than it could be. Some people dump their animals far away just to get rid of them, or move away and leave the pet there (one of the cats on my street is a victim of this - fortunately the neighbour has taken her in).
Perhaps consider adopting a kitten or older cat, or even a dog if they are for you. Animals can be so therapeutic and loving; I doubt I'd be here now if I never had the blessing of their company.
Also, you said your daughter has moved out. I'm not a parent so I'm not of a position to say much but, if she moved out and the reasoning was nothing to do with you, try to remember you're still loved very much by her. Perhaps it did happen because of a feud, but even then, family love often runs too deep. Often times people and family love each other, but simply need space as they grow older.
