They never say...for all we know she starved to death in Data's quarters and wasn't discovered untill the smell of death permeated the crew quarters' corridors! Or maybe she flew around and got killed during the battle. Don't know what she did when Picard called out, "All hands brace for impact!" Maybe she understood and wedged herself in somewhere like when the Enterprise-D crashed. Then again maybe she thought it was safe. After all, he didn't say, "All paws brace for impact!"
You don't think Ryker rescued her, do you?
